Step-by-step explanation:

because prime numbers are 2 ,3, 5, 7, 11, 13 ,17 ,19, 23 and so on. A co-prime is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be one. 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- prime.

for example the integers 6 10 15 are coprime because one is the only positive integer that divides all of them if every pair in a set of integers is coprime then the set is said to be fair vice coprime or pair Rai selectively prime mutually coprime on usually relative Li prime
