What is the Least Common Multiple of 611 and 615?
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 611 and 615 is 375765.
LCM(611,615) = 375765
Least Common Multiple of 611 and 615 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 611 and 615, than apply into the LCM equation.
GCF(611,615) = 1
LCM(611,615) = ( 611 × 615) / 1
LCM(611,615) = 375765 / 1
LCM(611,615) = 375765
Least Common Multiple (LCM) of 611 and 615 with Primes
