# What are the factors of 5 and 4?

## What are the factors of 5 and 4?

For 4 and 5 those factors look like this:

• Factors for 4: 1, 2, and 4.
• Factors for 5: 1 and 5.

What is the GCF of 4?

The GCF of 4 and 8 is 4. To calculate the greatest common factor of 4 and 8, we need to factor each number (factors of 4 = 1, 2, 4; factors of 8 = 1, 2, 4, 8) and choose the greatest factor that exactly divides both 4 and 8, i.e., 4.

### What is the LCM of 5 and 4?

20
The LCM of 4 and 5 is 20.

What are the common multiples of 5 and 4?

What is a “Common Multiple”? Say we have listed the first few multiples of 4 and 5: the common multiples are those that are found in both lists: The multiples of 4 are: 4,8,12,16,20,24,28,32,36,40,44,… The multiples of 5 are: 5,10,15,20,25,30,35,40,45,50,…

## How do you do GCF?

The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

How do you do the GCF method?

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 is the multiple of 5 and 4?

The LCM of 4 and 5 is 20. To find the LCM of 4 and 5, we need to find the multiples of 4 and 5 (multiples of 4 = 4, 8, 12, 16 . . . . 20; multiples of 5 = 5, 10, 15, 20) and choose the smallest multiple that is exactly divisible by 4 and 5, i.e., 20.

What are common multiples of 5 and 4?

## What is the LCM of 4 and 4?

4
Answer: LCM of 4 and 4 is 4. Explanation: The LCM of non-zero integers, x(4) and y(4), is the smallest positive integer m(4) that is divisible by both x(4) and y(4) without any remainder.

What is the LCM of 5 and 5?

5
LCM of 5 and 5 = 5. Therefore, 25 is the required number.

### What does GCF mean in math?

greatest common factor
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators.
