Breaking Down 20

Now, let's break down the number 20 into its factors. Factors can be either positive or negative, but for simplicity, we will focus on positive factors here.

The Factors of 20

To find the factors of 20, we need to identify the pairs of numbers that multiply together to give us 20.

1. 1 and 20

1 × 20 = 20

2. 2 and 10

2 × 10 = 20

3. 4 and 5

4 × 5 = 20

Prime Factorization

Breaking Down Further

We can also express 20 as a product of its prime factors. Prime factors are the smallest prime numbers that multiply together to form a given number.

20 = 2 × 2 × 5

In this case, the prime factors of 20 are 2 and 5.

Application of Factors

Real-Life Examples

Understanding factors is not just a mathematical exercise; it has practical applications in various real-life scenarios. Here are a few examples:

Multiplication: Factors help us solve multiplication problems more efficiently.
