What is the Least Common Multiple of 2700 and 2705?

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 2700 and 2705 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2700 and 2705, than apply into the LCM equation.

GCF(2700,2705) = 5
LCM(2700,2705) = ( 2700 × 2705) / 5
LCM(2700,2705) = 7303500 / 5
LCM(2700,2705) = 1460700
