Yes. The building blocks of 12 are 2, 2, and 3. If 13,512 is divisible by 2, 2, and 3, it is also divisible by 12.
In order to be divisible by 12, 13,512 must have two 2s as building blocks. Two 2s make a 4.
in order to test divisibility by 12, test the integer for 3 and 4.
When testing divisibility using larger building blocks that are not prime, remember to use building blocks that have no common divisor greater than 1.
