The highest **common** factor is found by multiplying all the factors that appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3, which is 12. The lowest **common multiple** is found by multiplying all the factors that appear in both lists: So the **LCM** of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5, which is 360.

Just so what is **LCM** and **GCF** with example?

Greatest Common Factor (**GCF**)

A **common multiple** is a number that is a **multiple** of two or more **numbers**. **Common multiples** of 2 and 3 are 0, 6, 12, 18. The least **common multiple** (**LCM**) of two **numbers** is the smallest number (non-zero) that is a **multiple** of both **numbers**.

Also, what is the **LCM** of 70 90 and 140?

The **LCM** of 90 and 140 is 1260.

Also what is the **LCM** of 8 and 12?

That least **common multiple** (**LCM**) of 8 and 12 is 24.

What is the **GCF** calculator?

The greatest **common** divisor (**GCF** or GCD or HCF) of a set of integers is the largest positive integer that can be divided into all **numbers** without a remainder. For example, for the **numbers** 18, 30, and 42, the gcd = 6.

## What is the gcd of 12?

Find the greatest **common** divisor

9 and 12 | 9: 1,3,9 12: 1,2,3,4,6,12 | 3 |

## What is a composite number in math?

Compound number. more An integer that can be formed by multiplying other integers. Example: 6 can be formed by 2 × 3, so it is a composite number. But 7 can’t be formed by multiplying other integers (1×7 would work, but we said we should use other integers), so it’s not a composite number, it’s prime.

## What is the LCM of 4 and 8?

**LCM** of 4 and 8 is 8. To get **LCM**, multiply the **common** prime factors of the two given **numbers** by the remaining unusual factors. Therefore **LCM** of 4 and 8 is 8.

## What is a prime factor?

A factor that is prime. In other words, any of the prime **numbers** that can be multiplied to give the original number. Example: The prime factors of 15 are 3 and 5 (because 3×5=15 and 3 and 5 are prime).

## What are the factors of 24?

24 Do you think Do you have a snow problem? Try this:

- 24 is a composite number.
- Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written as 24 = 2³ x 3.
- The exponents in prime factorization are 3 and 1.
- Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
- Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6.

## What is the LCM of 9 and 12?

The **LCM** of 9 and 12 is thirty-six.

## What is LCF?

Please read our privacy policy. A **common multiple** is a number that is a **multiple** of two or more **numbers**. The **common** multiples of 3 and 4 are 0, 12, 24, . The least **common multiple** (**LCM**) of two **numbers** is the smallest number (non-zero) that is a **multiple** of both.

## What does GCF mean?

greatest **common** factor

## What is LCM in mathematics?

Mathematical definition of terms. Least Common Multiple (**LCM**) The Least Common Multiple (**LCM**) of 2 **numbers** is the smallest number into which they are both evenly divisible. A good way to find the least **common multiple** of 2 **numbers** is to multiply both **numbers** by 1,2,3,4,5 and then find the first **multiple** that occurs in both lists.

## What is GCF used for? for?

A **common** use of the **GCF** is to simplify a fraction by dividing both the numerator and denominator by the **GCF** of both. Another way to find the **LCM** for two **numbers** is to divide the product of the two **numbers** by the **GCF** for the **numbers**. For example, the **GCF** of 36 and 60 is 12. The product of 36 x 60 = 2,160.

## What is the LCM of 6 and 9?

The **LCM** of 6 and 9 is 18.

## What is the GCF and LCM of 9 and 12?

Least **common multiple** of 9 and 12. The least **common multiple** (**LCM**) of 9 and 12 is 36.

## What is an LCM example?

Example: find the least **common multiple** of 4, 6 and 8. **Multiples** of 4 are: 4, 8 , 12, 16, 20, 24, 28, 32, 36, multiples of 6 are: 6, 12, 18, 24, 30, 36, multiples of 8 are: 8, 16, 24, 32, 40, . So the least **common multiple** (I can’t find a smaller one!) is 24

## What is the LCM of 12 and 15?

The least **common multiple** (**LCM**) of 12 and 15 is 60.
