What is the Least Common Multiple of 61000 and 61018?

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 61000 and 61018 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 61000 and 61018, than apply into the LCM equation.

GCF(61000,61018) = 2
LCM(61000,61018) = ( 61000 × 61018) / 2
LCM(61000,61018) = 3722098000 / 2
LCM(61000,61018) = 1861049000

Least Common Multiple (LCM) of 61000 and 61018 with Primes
