What is the Least Common Multiple of 615 and 634?
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 (LCM) of 615 and 634 is 389910.
LCM(615,634) = 389910
Least Common Multiple of 615 and 634 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 615 and 634, than apply into the LCM equation.
GCF(615,634) = 1
LCM(615,634) = ( 615 × 634) / 1
LCM(615,634) = 389910 / 1
LCM(615,634) = 389910
Least Common Multiple (LCM) of 615 and 634 with Primes
