What is the prime factorization for 128?

Prime factorization is breaking down a number into all of the prime numbers that make it up.

For example, in 128, since it is even, the easiest first step would be diving by two, a Prime number.

64 * 2 = 128. Now divide 64, another even number, by two.

32 * 2 * 2 = 128. Divide 32 by two.

16 * 2 * 2 * 2 = 128. Divide by two again.

8 * 2 * 2 * 2 * 2 = 128. Divide by two again.

4 * 2 * 2 * 2 * 2 * 2 = 128. Divide by two a final time.

2 * 2 * 2 * 2 * 2 * 2 * 2 = 128. This is your prime factorization.

But you write it condensed, so 27 would be the prime factorization for 128.
