The answer depends on W.
Prime factorization of 99 = 3 * 3 * 11
The three prime numbers which multiply to make 231 are 3 x 7 x 11.
111 = 3*37
As a product of its prime factors: 2*3*3*7 = 126
225 cannot be factorised into the product of only 3 prime numbers.
135
405
135
315
There are 4 of them which are 2*3*3*3 = 54
They are: 3*3*5*5 = 225
The prime factorization of 294 is 2 * 3 * 7 * 7. Therefore, the four prime numbers that multiply to make 294 are 2, 3, 7, and 7.
