LCM of 5 and 30 is the whole number that is divisible by 5 and 30 with no remainders left.

## Answer: LCM of 5 and 30 is 30.

We will understand two methods to find LCM of 5 and 30.

## Explanation:

Least Common Multiple of 5 and 30 is the smallest number which is exactly divisible by 5 and 30 leaving the remainder zero.

- LCM of 5 and 30 by Formula
- LCM of 5 and 30 by Listing Common Multiples

### Method1: LCM of 5 and 30 by Formula

We will use the formula of LCM (a, b):

LCM (a, b) = (a × b) / HCF (a, b)

HCF (a, b) is the highest common factor of a and b.

Use this formula to find the LCM of 60 and 700

LCM(5, 30) = (5 × 30) / HCF (5, 30)

LCM(5, 30) = 150/5

LCM(5, 30) = 30

Therefore, LCM of 5 and 30 is 30.

### Method2: LCM of 5 and 30 by Listing Common Multiples

Let's see the multiples of 5 and 30.

Multiples of 5 = 5, 10, 15, 20, 25, 30, ...

Multiples of 30 = 30, 60, ...

We can see, the lowest common multiple of 5 and 30 is 30.

### Thus, LCM of 5 and 30 is 30.
