Question

what are co .prime no​

Answer 1

Answer:

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.

Answer 2

Answer:

Numbers, which do not have any common factor between them other than one, are called co-prime numbers.

Explanation:

When two numbers (they may not be prime) do not have any common factor other than one between them they are called co-prime or relatively prime.

It is obvious that two prime numbers are always co-prime. For example,

17

and

23

.

However, even two composite numbers can also be co-prime or relatively prime. For example

16

and

25

do not have any common factor other than one. Similarly

84

and

65

do not have any common factor and are hence co-prime.
