Because 8 is 2 cubed, you can test if a number is divisible by 8 by dividing it by 2 three times. If the number you reach is an integer, then the number is divisible by 8. For example, 72/2 = 36/2 = 18/2 = 9. Therefore, 72 is divisible by 8. For very large numbers, if the last three digits are divisible by 8, the number itself is divisible by 8.

Prime factor each number. Circle the factors that are in all three numbers. Multiply those factors. 27=3x3x3 54=2x3x3 72=2x2x2x3x3 3x3=9 is the GCF

If the numbers are even, they are divisible by 2. So, the set of numbers must be divisible by both 2 and 3, which is the same as being divisible by 6. The set is {6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, ...}

All even numbers can be eliminated immediately because they are all divisible by 2. All numbers that end in 5 can be eliminated because they are divisible by 5. All numbers whose digits when added together are divisible by 3 can be eliminated because the number is divisible by 3. 53, 59, 61 67, 71 are the prime numbers.
