What is the divisibility rule for 32?

Answer 1

This works best for very large numbers. The divisibility rule for 32 is one I came up with myself- that is that if you can split the number in half FOUR times, and it is still even- it is a multiple of 32. Example- 64. 64÷2=32 that is the first one 32÷2=16 that is the second time. 16÷2=8 that is the third time. 8÷2=4 and that is the fourth time, four is even, so 64 is a multiple of 32. Please note- if you run into an odd number at any time during this process the number is not divisible by 32. That is because fractions, just like whole numbers, go to infinity. So no fraction can be broken down enough that it ends up a whole number.
