What is the Least Common Multiple of 291 and 303?
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 291 and 303 is 29391.
LCM(291,303) = 29391
Least Common Multiple of 291 and 303 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 291 and 303, than apply into the LCM equation.
GCF(291,303) = 3
LCM(291,303) = ( 291 × 303) / 3
LCM(291,303) = 88173 / 3
LCM(291,303) = 29391
Least Common Multiple (LCM) of 291 and 303 with Primes
