# What is the Least Common Multiple of 105 and 116?

*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 105 and 116 is **12180**.

LCM(105,116) = 12180

## Least Common Multiple of 105 and 116 with GCF Formula

The formula of **LCM** is LCM(a,b) = ( a × b) / GCF(a,b).

We need to calculate greatest common factor 105 and 116, than apply into the LCM equation.

GCF(105,116) = 1

LCM(105,116) = ( 105 × 116) / 1

LCM(105,116) = 12180 / 1

LCM(105,116) = 12180

## Least Common Multiple (LCM) of 105 and 116 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 105 and 116. First we will calculate the **prime factors of 105 and 116**.

### Prime Factorization of 105

Prime factors of 105 are 3, 5, 7. Prime factorization of **105** in exponential form is:

105 = 3^{1} × 5^{1} × 7^{1}

### Prime Factorization of 116

Prime factors of 116 are 2, 29. Prime factorization of **116** in exponential form is:

116 = 2^{2} × 29^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 105 and 116**.

LCM(105,116) = 3^{1} × 5^{1} × 7^{1} × 2^{2} × 29^{1}

LCM(105,116) = 12180
