What is the Least Common Multiple of 197 and 203?
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 197 and 203 is 39991.
LCM(197,203) = 39991
Least Common Multiple of 197 and 203 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 197 and 203, than apply into the LCM equation.
GCF(197,203) = 1
LCM(197,203) = ( 197 × 203) / 1
LCM(197,203) = 39991 / 1
LCM(197,203) = 39991
