Question

how to identify co prime numbers​

Answer 1

Answer:

co primes means 2numbers HCF should be 1

Answer 2

Answer:

Hey

Step-by-step 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. Consequently, any prime number that divides one does not divide the other.

Consider a set of two numbers, if they have no positive integer that can divide both, other than 1, the pair of numbers is co-prime.

Example 1: 21 and 22

For 21 and 22:

The factors of 21 are 1, 3, 7, and 21.

The factors of 22 are 1, 2, 11, and 22.

Here 21 and 22 have only one common factor that is 1. Hence, their HCF is 1 and are co-prime.
