### What are all the prime numbers of 56?

To find the prime numbers of 56, start with two numbers that
when multiplied together equal 56. For example:
2 x 28 = 56.
Two is prime, but 28 is composite, so it needs to be
factored.
2 x 2 x 14 = 56.
Now, 14 is prime, so factor it.
2 x 2 x 2 x 7 = 56.
All the factors are now prime, so the prime factors are 2 x 2 x
2 x 7.
