Question

what are co primes numbers

​

Answer 1

Co prime numbers -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. This is equivalent to their greatest common divisor (gcd) being

The numerator and denominator of a reduced fraction are coprime. As specific examples, 14 and 15 are coprime, being commonly divisible only by 1, while 14 and 21 are not coprime, because they are both divisible by 7.

we can given an example stating that - 7,9 as they both are only divisible by 1 in pairs

Answer 2

Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1.

Co-prime numbers are also known as relatively prime or mutually prime numbers.
