Make use of GCF of two or more numbers calculator to determine the Greatest Common Factor of 1, 5, 3 i.e. 1 largest integer that divides all the numbers equally.

GCF of 1, 5, 3 is 1

GCF(1, 5, 3) = 1

**Ex:** 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345

GCF of numbers 1, 5, 3 is 1

GCF(1, 5, 3) = 1

Given Input numbers are 1, 5, 3

To find the GCF of numbers using factoring list out all the factors of each number

**Factors of 1**

List of positive integer factors of 1 that divides 1 without a remainder.

1

**Factors of 5**

List of positive integer factors of 5 that divides 5 without a remainder.

1, 5

**Factors of 3**

List of positive integer factors of 3 that divides 3 without a remainder.

1, 3

**Greatest Common Factor**

We found the factors of 1, 5, 3 . The biggest common factor number is the **GCF** number.

So the **Greatest Common Factor 1, 5, 3 ** is **1**.

Therefore, GCF of numbers 1, 5, 3 is 1

Given Input Data is 1, 5, 3

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 1 is

Prime Factorization of 5 is 5

Prime Factorization of 3 is 3

The above numbers do not have any common prime factor. So GCF is 1
