primes into 875
2 and 3 do not work, so we try 5:
875/5 = 175
175/5 = 35
35/5 = 7
7/7 = 1
So, 5*5*5*7
or 5^3*7

875 is not even, so 2 is not a factor.

8 + 7 + 5 = 20. 2 + 0 = 2. 2 is not divisible by 3, so 875 is not divisible by 3.

875 ends in 5, so it is divisible by 5. 875/5 = 175.

175 ends in 5, so it is divisible by 5. 175/5 = 35.

35/5 = 7

The complete prime factorization of 875 is thus , and to answer your question precisely, 5 and 7.
