Question

Wheather the pair of number given below are coprime number 14,21

Answer 1

Answer:

yes they are coprime number

Answer 2

Answer with explanation :

In mathematics, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides a does not divide b, and vice versa. This is equivalent to their greatest common divisor being 1.

• Factors of 14 = 1, 2, 7, 14
• Factors of 21 = 1, 3, 7, 21

Since, the common factors are 1 and 7.

therefore they are not Co prime numbers.
