What is the Least Common Multiple of 319 and 331?
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 319 and 331 is 105589.
LCM(319,331) = 105589
Least Common Multiple of 319 and 331 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 319 and 331, than apply into the LCM equation.
GCF(319,331) = 1
LCM(319,331) = ( 319 × 331) / 1
LCM(319,331) = 105589 / 1
LCM(319,331) = 105589
