# What is the LCM of 30 and 3?

## What is the LCM of 30 and 3?

30
Answer: LCM of 3 and 30 is 30.

## What two numbers have an LCM of 30?

The LCM of 2 and 30 is 30.

How do I find the 2 numbers when their LCM and HCF are given?

First we need to find the highest common factor (H.C.F.) of 15 and 18 which is 3. Then we need to find the lowest common multiple (L.C.M.) of 15 and 18 which is 90. Therefore, product of H.C.F. and L.C.M. of 15 and 18 = product of 15 and 18. or, L.C.M.

What is the GCF of 3 and 30?

3
The GCF of 3 and 30 is 3.

### What is the LCM of 3 and 8?

24
So the lowest common multiple of 3 and 8 is 24.

### What is the formula of LCM and HCF?

HCF and LCM Formula and Tricks Product of two numbers = Product of their HCF and LCM. Two numbers are said to be co-prime if their HCF is 1. HCF = HCF of Numerators/LCM of denominators. LCM = LCM of Numerators/ HCF of Denominators.

How do you find HCF and LCM?

The formula that shows the relationship between their LCM and HCF is: LCM (a,b) × HCF (a,b) = a × b. For example, let us take two numbers 12 and 8. Let us use the formula: LCM (12,8) × HCF (12,8) = 12 × 8. The LCM of 12 and 8 is 24; and the HCF of 12 and 8 is 4.
