What is the Least Common Multiple of 2 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 2 and 58 is 58.
LCM(2,58) = 58
Least Common Multiple of 2 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 2 and 58, than apply into the LCM equation.
GCF(2,58) = 2
LCM(2,58) = ( 2 × 58) / 2
LCM(2,58) = 116 / 2
LCM(2,58) = 58
Least Common Multiple (LCM) of 2 and 58 with Primes
Least common multiple can be found by multiplying the highest exponent prime factors of 2 and 58. First we will calculate the prime factors of 2 and 58.
Prime Factorization of 2
Prime factors of 2 are 2. Prime factorization of 2 in exponential form is:
2 = 21
Prime Factorization of 58
Prime factors of 58 are 2, 29. Prime factorization of 58 in exponential form is:
58 = 21 × 291
Now multiplying the highest exponent prime factors to calculate the LCM of 2 and 58.
LCM(2,58) = 21 × 291
LCM(2,58) = 58
