What is the Least Common Multiple of 215 and 221?
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 215 and 221 is 47515.
LCM(215,221) = 47515
Least Common Multiple of 215 and 221 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 215 and 221, than apply into the LCM equation.
GCF(215,221) = 1
LCM(215,221) = ( 215 × 221) / 1
LCM(215,221) = 47515 / 1
LCM(215,221) = 47515
Least Common Multiple (LCM) of 215 and 221 with Primes
