Is (18,25) a coprime ?? |
|
Answer»
Two INTEGERS a and b are said to be coprimes if they have no common FACTORS other than 1 and the number itself. Hence their HCF(Highest common factor) is 1. Here, (18,25) is a coprime. Prime factorisation of: 18= 2×3×3 25= 5×5 18 and 25 have no common factor other than 1. =>HCF(18,25)=1 Yes, (18,25) are coprime NUMBERS. |
