What is the Least Common Multiple of 3101 and 3105?

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 3101 and 3105 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 3101 and 3105, than apply into the LCM equation.

GCF(3101,3105) = 1
LCM(3101,3105) = ( 3101 × 3105) / 1
LCM(3101,3105) = 9628605 / 1
LCM(3101,3105) = 9628605

Least Common Multiple (LCM) of 3101 and 3105 with Primes
