Least Common Multiple of 1 and 100

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 1 and 100 is 100.

LCM(1,100) = 100

Least Common Multiple of 1 and 100 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 1 and 100, than apply into the LCM equation.

GCF(1,100) = 1
LCM(1,100) = ( 1 × 100) / 1
LCM(1,100) = 100 / 1
LCM(1,100) = 100

Least Common Multiple (LCM) of 1 and 100 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 1 and 100. First we will calculate the prime factors of 1 and 100.

Prime Factorization of 100

Prime factors of 100 are 2, 5. Prime factorization of 100 in exponential form is:

100 = 22 × 52

Now multiplying the highest exponent prime factors to calculate the LCM of 1 and 100.

LCM(1,100) = 22 × 52
LCM(1,100) = 100
