Question

find the hcf of 110 224 315​

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.

Finding HCF by factorisation method .

110=2×5×11×1

224=7×2^5×1

315=3²×5×7×1

Lowest power= 1 (as only 1 is common in all three nos.)

Thank you :)
