Question

What is co prime numbers?

Answer 1

co-prime numbers are numbers which have no positive factors in common other than `1`

Explanation:

co-prime numbers are also sometimes called relatively prime.

As an example:
`12` has positive factors: `1, 2, 3, 4, and 6`
and
`35` has positive factors: `1, 5, and 7`

Since the only positive factor `12` and `35` share is `1`,
they are co-prime.

Answer 2

As described below.

Explanation:

In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1.

This is equivalent to their greatest common divisor (gcd) being 1.
