## What do 5 and 4 have in common?

Greatest common factor (GCF) of 4 and 5 is 1.

**What are factor of 5?**

1 and 5

Factors of 5 are the natural numbers that can divide the actual number, evenly. 5 is the third prime number when arranged in ascending order. Therefore, 5 will have only two factors, 1 and 5. If we divide 5 by any other integer, then the remainder will be a non-zero positive integer.

**What are the factors for 4?**

In other words, if we multiply a pair of numbers together, which results in the original number 4, the numbers are the factors of 4. As 4 is an even composite number, it has more than two factors. Thus, the factors of 4 are 1, 2 and 4.

### What are the first 5 factors of 4?

**What are the multiples of 4 and 5?**

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 is the least common factor of 4 and 5?**

Least Common Multiple (LCM) of 4 and 5 is 20.

## What are the factor pairs of 5?

Factors of 5 in Pairs Positive factors of 5 : 1 and 5.

**What’s the LCM of 4 and 5?**

From the above-given multiples of 4 and 5 is the multiple 20 is the smallest common multiple. Therefore, LCM. of 4 and 5 is 20.

**What are multiples of 5?**

The multiples of 5 include 5, 10, 15, 20, 25, 30, 35, 40,…. The multiples of 10 include 10, 20, 30, 40, 50, 60,….

### What is the least common multiple of 4 & 5?

What is the LCM of 4 and 5? Answer: LCM of 4 and 5 is 20.

**What is the factor of 6?**

The factors of 6 are the numbers that divide 6 exactly without leaving the remainder. In other words, the factors of 6 are the numbers that are multiplied in pairs resulting in an original number 6. As 6 is an even composite number, it has many factors other than 1 and 6. Thus, the factors of 6 are 1, 2, 3 and 6.

**What are the factors of 3 and 5?**

The factors of 3 and 5 are 1, 3 and 1, 5 respectively. There are 3 commonly used methods to find the GCF of 3 and 5 – prime factorization, long division, and Euclidean algorithm.
