There's only one single number that equals 75. That number is 75, and it's not a prime number. If you mean which prime numbers multiplied together equal 75, 52 X 3 works.
All composite numbers can.
1/4 of all numbers are factored by 4 and 1/6 of all numbers are factored by 6
The answer is 450. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.

x2 + 1 can't be factored in the real numbers. If complex numbers are acceptable, it can be factored as (x + i)(x - i).
All composite numbers can.
