# Is 707 a prime number?

It is possible to find out using mathematical methods whether a given integer is a prime number or not.

For 707, the answer is: No, 707 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 707) is as follows: 1, 7, 101, 707.

For 707 to be a prime number, it would have been required that 707 has only two divisors, i.e., itself and 1.

As a consequence:

For 707 to be a prime number, it would have been required that 707 has only two divisors, i.e., itself and 1.

However, 707 is a **semiprime** (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 707 = 7 x 101, where 7 and 101 are both prime numbers.

### Is 707 a deficient number?

Yes, 707 is a deficient number, that is to say 707 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 707 without 707 itself (that is 1 + 7 + 101 = 109).
