What is the Least Common Multiple of 48 and 62?
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 48 and 62 is 1488.
LCM(48,62) = 1488
Least Common Multiple of 48 and 62 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 48 and 62, than apply into the LCM equation.
GCF(48,62) = 2
LCM(48,62) = ( 48 × 62) / 2
LCM(48,62) = 2976 / 2
LCM(48,62) = 1488
Least Common Multiple (LCM) of 48 and 62 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 48 and 62. First we will calculate the prime factors of 48 and 62.
Prime Factorization of 48
