What is the Least Common Multiple of 615 and 622?
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 622 is 382530.
LCM(615,622) = 382530
Least Common Multiple of 615 and 622 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 622, than apply into the LCM equation.
GCF(615,622) = 1
LCM(615,622) = ( 615 × 622) / 1
LCM(615,622) = 382530 / 1
LCM(615,622) = 382530
Least Common Multiple (LCM) of 615 and 622 with Primes
