What is cooprime number

1.	What is cooprime number
Answer» Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their\xa0highest common factor\xa0(HCF) will be 1. Co-prime numbers are also known as relatively prime or mutually prime numbers. It is important that there should be two numbers in order to form co-primes.Example 1:\xa021 and 22For 21 and 22:\tThe factors of 21 are 1, 3, 7 and 21.\tThe 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. Two or more numbers having only 1 as their common factor
