What is the Least Common Multiple of 203 and 215?
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 203 and 215 is 43645.
LCM(203,215) = 43645
Least Common Multiple of 203 and 215 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 203 and 215, than apply into the LCM equation.
GCF(203,215) = 1
LCM(203,215) = ( 203 × 215) / 1
LCM(203,215) = 43645 / 1
LCM(203,215) = 43645
Least Common Multiple (LCM) of 203 and 215 with Primes
