What is the Least Common Multiple of 91000 and 91016?

Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor.

Least Common Multiple of 91000 and 91016 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 91000 and 91016, than apply into the LCM equation.

GCF(91000,91016) = 8
LCM(91000,91016) = ( 91000 × 91016) / 8
LCM(91000,91016) = 8282456000 / 8
LCM(91000,91016) = 1035307000

Least Common Multiple (LCM) of 91000 and 91016 with Primes
