Is 32 divisible by 2 or 3 or 4 or 5 or 6 or 9 or 10?

Here are some ways of remembering which numbers are divisible by others:

  • Divisible by 2: Is the number even? 32 ends in a 0, 2, 4, 6, or 8, so 32 is divisible by 2
  • Divisible by 3: Do the digits add up to be multiple of three? 3 + 2 = 5, and 5 cannot divide by 3, so 32 is NOT divisible by 3
  • Divisible by 4: Are the last two digits divisible by 4? (For this, one has to memorize numbers between 1-100) 32 is divisible by 4
  • Divisible by 5: Does the number end in a 5 or 0? 32 ends in a 2, so it is NOT divisible by 5
  • Divisible by 6: Is the number divisible by 2 AND 3? (See above) 32 is not divisible by 3, so it is NOT divisible by 6
  • Divisible by 9: Do the digits add up to be a multiple of 9? (See above) 32 is not a multiple of 3, so it is NOT divisible by 9
  • Divisible by 10: Does the number end in a 0? 32 ends in a 2, so it is NOT divisible by 10.

The answer is, 32 is divisible by 2 and 4
