What is the Least Common Multiple of 394 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 394 and 401 is 157994.
LCM(394,401) = 157994
Least Common Multiple of 394 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 394 and 401, than apply into the LCM equation.
GCF(394,401) = 1
LCM(394,401) = ( 394 × 401) / 1
LCM(394,401) = 157994 / 1
LCM(394,401) = 157994
Least Common Multiple (LCM) of 394 and 401 with Primes
