If the last digit is a 0, 2, 4, 6, or 8 the number is divisible by two. Example: 210 is divisible by two because the last digit in the number is a 0. The sum of the digits of the number is divisible by three. Example: 93 , 9+3=12 , so 12 is divisible by three because 3 goes in to twelve evenly. The last two digits are a multiple of 4 then the whole number divides by 4. Example: 924 is divisible by four because 24 is a multiple of 4. The last digit of the number is 5 or 0. Example : 70 is divisible by 5 because the last digit is a zero. The number is divisible by both two and three Example: 12 is divisible by both 2 and 3 so we know it is divisible by 6 The sum of the digits of the numbers is divisible by nine. Example: 81 is like 8+1= 9 so you know that 9 can go into 81 evenly. The last digit in the number is a zero Example: 50 ends in a zero so it is divisible by 10 1. 2. 3. 4. 5. 6. 7. 8. 140 144 282 315 1578 4860 8745 9990 9. There are 117 students going to summer camp.
