Choose a factor pair of 640 and then factor pairs of each resulting number that is not prime until you have reduced 640 to prime numbers.

640
10 x 64
2x5 x 8x8
_ _ 2x4 2x4
_ _ _ 2x2 _ 2x2

So, the prime factorization of 640 is 2 x 5 x 2 x 2 x 2 x 2 x 2 x 2, which is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 when reordered in numerical order. It can also be written in index form (in other words, using exponents) 27 x 5.
