# Factors of 1

Factors of 1 are the number itself as it is neither a prime nor a composite number. You must teach kids factors of 1 and the methods to calculate them for effective learning experiences. Kids must enjoy the learning process and retain the factors of a number in their memory for a long time. To make learning fun, you can conduct math activities for kids.

Contents

Besides recognizing factors of 1, kids must get familiar with pair and prime factors of 1. Since the number 1 is not a prime number, it is not possible to find the prime factors of 1 using the prime factorization method. However, you can find the pair factors of 1 using the multiplication method. The best way would be to conduct number games for kids to help them recognize the factors of 1 effectively.

## What are the Factors of 1?

Factors of 1 are the numbers that divide the original number 1 with the integer without leaving the remainder. Since the number 1 is neither prime nor composite, the factor of 1 is the number itself. The pair factor of 1 is (1, 1), and the negative pair factor is (-1, -1). However, there are no prime factors of 1 because the number 1 is neither prime nor composite. As the factor of 1 is the number itself, you can calculate the pair and prime factors using the multiplication and division methods, respectively. Kids must get familiar with the 1 times table to understand the concept of factors of 1.

## How to Find the Factors of 1?

To calculate the factors of 1, you need to divide the original number completely without leaving the remainder. Check out the following method to find the factors of 1.

1/1 = 1

Therefore, the factor of 1 is the number itself. You must also keep in mind that the number 1 is the factor for all other numbers. The pair factors of 1 are the numbers obtained when you multiply two integers in pairs to get the original number. In this case, the number 1 is multiplied by an integer 1 to get the original number. Hence, the pair factors of 1 is 1 x 1 = (1, 1) and the negative factors of 1 is (-1, -1). When two negative numbers multiply together, the result you get is positive. Besides this, kids must understand that there are no prime factors of 1 since the number 1 is not a prime number.

## Solved Examples on Factors of 1

Some solved examples on factors of 1 for kids are mentioned below:

Example 1: Find the common factors of 21 and 1.

Solution: Factors of 21 = 1, 3, 7, and 21.

Factors of 1 = 1

Therefore, the common factors of 21 and 1 are 1.

Example 2: Find the common factors of 28 and 1.

Solution: Factors of 28 = 1, 2, 4, 7, 14, and 28

Factors of 1 = 1

Therefore, the common factors of 28 and 1 are 1.
