What is the Least Common Multiple of 205 and 224?
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 205 and 224 is 45920.
LCM(205,224) = 45920
Least Common Multiple of 205 and 224 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 205 and 224, than apply into the LCM equation.
GCF(205,224) = 1
LCM(205,224) = ( 205 × 224) / 1
LCM(205,224) = 45920 / 1
LCM(205,224) = 45920
Least Common Multiple (LCM) of 205 and 224 with Primes
