What is the Least Common Multiple of 321 and 332?
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 321 and 332 is 106572.
LCM(321,332) = 106572
Least Common Multiple of 321 and 332 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 321 and 332, than apply into the LCM equation.
GCF(321,332) = 1
LCM(321,332) = ( 321 × 332) / 1
LCM(321,332) = 106572 / 1
LCM(321,332) = 106572
Least Common Multiple (LCM) of 321 and 332 with Primes
