Best Answer

Divid 128 repeatedly by the smallest prime numbers you can find until you get to 1. Like this:


128 / 2

64 / 2
32 / 2
16 / 2
8 / 2
4 / 2
2 / 2

You can see from this that the only prime factor of 128 is 2

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.
