This has been sitting here long enough. I'm going to guess that you are asking about factor strings relating to 3^2, 5^3 and 7^2 which are the prime factorizations of 9, 125 and 49 respectively.

3 x 3 = 9

7 x 7 = 49

5 x 25 = 125

5 x 5 x 5 = 125

There is a chance you were asking about 3^2 x 5^3 x 7^2 which is the prime factorization for 55125 and has a lot of other factor strings. If that was the case, please re-submit your question.
