What is co. Primes? |
|
Answer» Co-prime number is a set of numbers or integers which have only 1 as their common factor. That is their highest common factor (HCF) will be 1. It is also known as relatively prime or mutually prime numbers.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.Ex 1: 21 and 2221 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. No which have there common hcf . |
