What is the Least Common Multiple of 101 and 110?

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 of 101 and 110 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 101 and 110, than apply into the LCM equation.

GCF(101,110) = 1
LCM(101,110) = ( 101 × 110) / 1
LCM(101,110) = 11110 / 1
LCM(101,110) = 11110

Least Common Multiple (LCM) of 101 and 110 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 101 and 110. First we will calculate the prime factors of 101 and 110.

Prime Factorization of 101

Prime Factorization of 110

Now multiplying the highest exponent prime factors to calculate the LCM of 101 and 110.

LCM(101,110) = 101¹ × 2¹ × 5¹ × 11¹
LCM(101,110) = 11110
