Professor Greenline Explaining Math Concepts

Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 1, how they are used in real life, and tips to learn them quickly.

What are the Factors of 1?

The numbers that divide 1 evenly are known as factors of 1. A factor of 1 is a number that divides the number without remainder. The only factor of 1 is 1 itself. Negative factors of 1: -1. Prime factors of 1: 1 has no prime factors because it is neither a prime nor a composite number. The sum of factors of 1: 1 = 1

How to Find Factors of 1?

Factors can be found using different methods. Mentioned below are some commonly used methods: Finding factors using multiplication Finding factors using division method

Professor Greenline from BrightChamps

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1. Identifying the numbers which are multiplied to get the number 1 is the multiplication method. Step 1: Multiply 1 by 1, 1 × 1 = 1. Therefore, the positive factor pair of 1 is: (1, 1). For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given number with whole numbers until the remainder becomes zero and listing out the numbers which result as whole numbers as factors. Factors can be calculated by following a simple division method - Step 1: Divide 1 by 1, 1 ÷ 1 = 1. Therefore, the factor of 1 is: 1.

Prime Factors and Prime Factorization

Since 1 is neither prime nor composite, it does not have a prime factorization.

Factor Tree

The factor tree is a graphical representation of breaking down any number into prime factors. However, since 1 is neither prime nor composite, a factor tree is not applicable.
