Factors, Multiples and Primes (F/E)
I know what odds, evens and multiples of a number are: (Level 4)
1) Look at the list of numbers below:
1, 2, 5, 10, 15, 16, 17, 20, 21, 30
a) Which numbers in the list are multiples of 5? b) Which numbers in the list are even numbers?
c) Which numbers in the list are odd?
d) Which numbers in the list are multiples of 3?
e) Which numbers in the list are multiples of both 2 and 5?
I can find all of the factors of a number: (Level 5)
2) a) Write down a pair of numbers that multiply together to make 32.
How many different pairs of numbers can you find?
b) Write down all the factors of 24
b) Write down all the factors of 40
I know what prime numbers are: (Level 5)
3) Write down all the prime numbers less than 30.
I can find Highest Common Factors and Lowest Common Multiples (Level 5)
4) For each pair of numbers write down the HCF and the LCM
a) 20 14
b) 12 and 18
c) 24 and 36
