Q1 Find the product of individual digits of given number
Step 1
To find the product of the individual digits from the given number, first have to have to identify each
digit in the given number and then multiply.
Step 2
Input: - A Decimal Number
Process: - The decimal number should be divided by 10 to find the reminder, and must be multiplied
with X, and then the number should be rounded to the nearest integer and repeat the process until the
number is 0 or not greater than 0.
Output: - Display the results.
Step 3
Input
Decimal Number
Process
Identify and multiply individual
Digits.
Output
Product
Step 4; Algorithm
Step 1 Start
Step 2 R = 0, X = 1
Step 3 Input N
Step 4 R= N % 10
Step 5 X = X * R
Step 6 ROUND(N) = N/10
Step 7 N > 0 GoTo Step 4 or GoTo Step 8
Step 8 PRINT “Product of individual digits in a number” ;X
Step 9 End
Step 5: Testing Algorithm
Sample Value1: - 142
Sample output Value: - 8
R & X variables were initialized to 0 and 1. R is for Reminder and X is for the final product. As the number N
entered It will be divided by 10 and we use % function to find the reminder which then multiplies with X. N will be
further divided by 10 and rounded to nearest integer. Then a conditional statement is written if N meets the
condition then process repeats otherwise the final product of the digits is displayed.

Q 3. Check the given number is Abundant Number or Not.
Step 1
We need an input to enter the number. The number is divided, if the reminder is 0 then the divisor will
be added to total and the process continues until the divisor is greater than the given number.
Step 2
Input: - A Decimal Number
Process: - The number will be divided by X and it increments by 1 until the X is greater than the given
number. Total of the divisors is then calculated and checks if the number is abundant or not.
Output: - Display the results (Statement saying Abundant Number or Not)
Step 3
Input
Decimal Number
Process
Output
The number will be divided by X and it
increments by 1 until the X is greater
than the given number. Total of the
divisors is then calculated and checks if
the number is abundant or not.

i > N GOTO step 10 or GOTO step 4
Total > N GOTO step 11 Or GOTO step 14
Print “This number is an Abundant Number”
GOTO step 14
Print “This number is not an abundant number”
End
Step 5: Testing Algorithm
Sample Value1: - 10
Sample output Value: - This number is not an abundant number
R, X, I, T variables were initialized. R is
for Reminder. As the number N
entered it is divided by X (Divisor) if the
reminder is 0 then X is added to T, If
reminder is not 0 then x will be
incremented and further divides the
number. At the end T which is the
total of the appropriate divisors is
compared against the given number to
check if the number is abundant or
not.

Q4 Check the given number is Prime or Not.
Step 1
We have to enter a decimal number. It should be divided by the divisor which increments by 1 from 0
until it is > to the given number.
Step 2
Input: - A Decimal Number
Process: - The decimal number will be divided by the divisor(X which increments by 1 from 0 until X
greater than the given number) to take note of the reminder. If the count of reminders which are 0
greater than 2 than it prints it is a prime number or not.
Output: - Statement saying “Prime or Not”
Step 3
Input
Decimal Number
Continuation is On the Next Page
Process
Output
The decimal number will be divided by
the divisor(X which increments by 1
from 0 until X greater than the given
number) to take note of the reminder. If
the numbers of reminder which are 0
are greater than 2 than it prints it is a
prime number or not.

Step 5: Testing Algorithm
Sample Value1: - 18
Sample output Value: - Not a Prime number.
R, X, and I variables were initialized. R is for Reminder. I made use of the WHILE Loop for this
problem. The number will be kept on dividing by X and I (reminder is stored) will be
incremented by 1 if the reminder is 0. At the end when X is greater than the given number
while loop stops and displays the results by comparing the variable I to the number 2, If they
are equal then number is said to be prime otherwise it is not prime. The reason for this is that
Prime number is only divisible by 2 numbers which are 1 and the number itself, so, thereby
having reminders more than 2 it means the number is not prime.

Q5 Find the factorial of a given number
Step 1
To find the factorial of the given number, we need an input to enter the number. All the numbers that
are less than given number should be multiplied to find the factorial.
Step 2
Input: - A Decimal Number
Process: - As the number entered, Y will be incremented by 1 and then compared with the given number
if less than or equal to it, then Z will be multiplied with Y, process continues until the condition is not
met.
Output: - Factorial Value
Step 3
Input
Decimal Number
Continuation is On the Next Page
Process
As the number entered, Y will be
incremented by 1 and then compared
with the given number if less than or
equal to it, then Z will be multiplied with
Y, process continues until the condition
is not met.
Output

Step 5: Testing Algorithm
Sample Value: - 8
Sample output Value: - 40320
Y and Z were initialized to 0 and 1. When the number is entered, Y will be incremented by 1. Then a decision is
made by comparing Y with the given number, if the condition is true then Z will be multiplied with Y. The
process continues until the condition is false or not true, displaying the output which is a factorial value of the
given number.
