What is the Least Common Multiple of 721 and 725?
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 721 and 725 is 522725.
LCM(721,725) = 522725
Least Common Multiple of 721 and 725 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 721 and 725, than apply into the LCM equation.
GCF(721,725) = 1
LCM(721,725) = ( 721 × 725) / 1
LCM(721,725) = 522725 / 1
LCM(721,725) = 522725
Least Common Multiple (LCM) of 721 and 725 with Primes
