What is the Least Common Multiple of 92000 and 92005?

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 92000 and 92005 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 92000 and 92005, than apply into the LCM equation.

GCF(92000,92005) = 5
LCM(92000,92005) = ( 92000 × 92005) / 5
LCM(92000,92005) = 8464460000 / 5
LCM(92000,92005) = 1692892000

Least Common Multiple (LCM) of 92000 and 92005 with Primes
