Question

find the LCM and HCF by 5 by prime factorization of 275, 225, 175​

Answer 1

Hi there !!

Fundamental theorem of arithmetic :

Every composite number can be expressed as a product of primes, and this factorisation is unique except for the order in which the prime factors occur.

275 = 5²×11

225 = 5²×3²

175 = 5²×7

L.C.M (Highest power)=5²×11×3²×7

H.C.F (Lowest power)=5²=25

Thankyou :)
