# What is the Least Common Multiple of 80 and 93?

*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 80 and 93 is **7440**.

LCM(80,93) = 7440

## Least Common Multiple of 80 and 93 with GCF Formula

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

We need to calculate greatest common factor 80 and 93, than apply into the LCM equation.

GCF(80,93) = 1

LCM(80,93) = ( 80 × 93) / 1

LCM(80,93) = 7440 / 1

LCM(80,93) = 7440

## Least Common Multiple (LCM) of 80 and 93 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 80 and 93. First we will calculate the **prime factors of 80 and 93**.

### Prime Factorization of 80

Prime factors of 80 are 2, 5. Prime factorization of **80** in exponential form is:

80 = 2^{4} × 5^{1}

### Prime Factorization of 93

Prime factors of 93 are 3, 31. Prime factorization of **93** in exponential form is:

93 = 3^{1} × 31^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 80 and 93**.

LCM(80,93) = 2^{4} × 5^{1} × 3^{1} × 31^{1}

LCM(80,93) = 7440
