why isn't 51 a prime number?

Sagot :

The common misconception is that odd numbers are prime number, which is not always true.

51 is an odd number, but not a prime number.

By definition, prime number is a counting number greater than one with only two factors, 1 and itself.

51 has four factors : 1, 3, 17, 51.

Therefore, 51 is not a prime number.
