What is the Least Common Multiple of 12900 and 12907?

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 12900 and 12907 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 12900 and 12907, than apply into the LCM equation.

GCF(12900,12907) = 1
LCM(12900,12907) = ( 12900 × 12907) / 1
LCM(12900,12907) = 166500300 / 1
LCM(12900,12907) = 166500300

Least Common Multiple (LCM) of 12900 and 12907 with Primes
