What is the Least Common Multiple of 2080 and 2095?

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 2080 and 2095 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 2080 and 2095, than apply into the LCM equation.

GCF(2080,2095) = 5
LCM(2080,2095) = ( 2080 × 2095) / 5
LCM(2080,2095) = 4357600 / 5
LCM(2080,2095) = 871520
