What is the most common multiple of 12 and 30?

60
The LCM of 12 and 30 is 60.

### What is the least common factor of 12 and 30?

For example, for LCM (12,30) we find:

• Prime factorization of 12 = 2 × 2 × 3.
• Prime factorization of 30 = 2 × 3 × 5.
• Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.
• Therefore LCM (12,30) = 60.

### What is the common factor of 12 and 12?

What is the GCF of 12 and 12? The GCF of 12 and 12 is 12.

How do you find common factors?

To find the common factors of two numbers, you first need to list all the factors of each one and then compare them. If a factor appears in both lists then it is a common factor.

## How do you find the common factors?

Here’s how to find the GCF of a set of numbers using prime factorization:

1. List the prime factors of each number.
2. Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
3. Multiply all the circled numbers. The result is the GCF.

## What are the common factors of 6 12 and 30?

What is the Greatest Common Factor?

• Factors for 6: 1, 2, 3, and 6.
• Factors for 12: 1, 2, 3, 4, 6, and 12.
• Factors for 30: 1, 2, 3, 5, 6, 10, 15, and 30.

What is a common denominator for 30?

Multiples of 6 are 12, 18, 24, 30, 36, 42, 48,… Multiples of 15 are 30, 45, 60, 75, 90,…. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6 and 1/15 is 30.

### What is the least common multiple of 8 and 12?

24
The first multiple that 8 and 12 have in common is 24. Notice that 48 is also a common multiple; however, 24 is the smallest number that they have in common. This makes it the least common multiple.

### What is the common factor of 12 and 36?

There are 6 common factors of 12 and 36, that are 1, 2, 3, 4, 6, and 12. Therefore, the highest common factor of 12 and 36 is 12.

What are the common factor of 12 and 18?

6
In terms of numbers, the greatest common factor (gcf) is the largest natural number that exactly divides two or more given natural numbers. Example 1: 6 is the greatest common factor of 12 and 18. Example 2: 2 is a common factor of 12 and 18, but it is NOT the GREATEST common factor.
