What is the Least Common Multiple of 389 and 401?
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 389 and 401 is 155989.
LCM(389,401) = 155989
Least Common Multiple of 389 and 401 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 389 and 401, than apply into the LCM equation.
GCF(389,401) = 1
LCM(389,401) = ( 389 × 401) / 1
LCM(389,401) = 155989 / 1
LCM(389,401) = 155989
Least Common Multiple (LCM) of 389 and 401 with Primes
