What is the Least Common Multiple of 53 and 58?
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 53 and 58 is 3074.
LCM(53,58) = 3074
Least Common Multiple of 53 and 58 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 53 and 58, than apply into the LCM equation.
GCF(53,58) = 1
LCM(53,58) = ( 53 × 58) / 1
LCM(53,58) = 3074 / 1
LCM(53,58) = 3074
Least Common Multiple (LCM) of 53 and 58 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 53 and 58. First we will calculate the prime factors of 53 and 58.
Prime Factorization of 53
