What is the Least Common Multiple of 54 and 59?
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 54 and 59 is 3186.
LCM(54,59) = 3186
Least Common Multiple of 54 and 59 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 54 and 59, than apply into the LCM equation.
GCF(54,59) = 1
LCM(54,59) = ( 54 × 59) / 1
LCM(54,59) = 3186 / 1
LCM(54,59) = 3186
Least Common Multiple (LCM) of 54 and 59 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 54 and 59. First we will calculate the prime factors of 54 and 59.
Prime Factorization of 54
