The prime factorization of 245 is 5^1 * 7^2.

5 x 72 = 245

175/245 = 35/49 = 5/7 these are both prime numbers

To find the prime factorization it helps to first divide by obvious divisors. In this case, the number ends in a 5, so we know it can divide by 5. Do this and you get 49. This is known from times tables to be 7x7. Thus the prime factorization of 245 is 5x7x7.
