# What is the Least Common Multiple of 58 and 62?

*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 58 and 62 is **1798**.

LCM(58,62) = 1798

## Least Common Multiple of 58 and 62 with GCF Formula

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

We need to calculate greatest common factor 58 and 62, than apply into the LCM equation.

GCF(58,62) = 2

LCM(58,62) = ( 58 × 62) / 2

LCM(58,62) = 3596 / 2

LCM(58,62) = 1798

## Least Common Multiple (LCM) of 58 and 62 with Primes

Least common multiple can be found by multiplying the highest exponent prime factors of 58 and 62. First we will calculate the **prime factors of 58 and 62**.

### Prime Factorization of 58

Prime factors of 58 are 2, 29. Prime factorization of **58** in exponential form is:

58 = 2^{1} × 29^{1}

### Prime Factorization of 62

Prime factors of 62 are 2, 31. Prime factorization of **62** in exponential form is:

62 = 2^{1} × 31^{1}

Now multiplying the highest exponent prime factors to calculate the **LCM of 58 and 62**.

LCM(58,62) = 2^{1} × 29^{1} × 31^{1}

LCM(58,62) = 1798
