What is the Least Common Multiple of 411 and 421?
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 411 and 421 is 173031.
LCM(411,421) = 173031
Least Common Multiple of 411 and 421 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 411 and 421, than apply into the LCM equation.
GCF(411,421) = 1
LCM(411,421) = ( 411 × 421) / 1
LCM(411,421) = 173031 / 1
LCM(411,421) = 173031
Least Common Multiple (LCM) of 411 and 421 with Primes
