What are the Factors of 20?
Factors of 20 are the numbers obtained when the original number 20 is divided by the integers without leaving a remainder. The factors of 20 are 1, 2, 4, 5, 10, and 20. As the number is a composite number, it has many factors other than one and the number itself. We can also say that the numbers are multiplied in pairs to get the original number, known as pair factors of 20. The pair factors of 20 are (1, 20), (2, 10), and (4, 5). Also, there are negative factors of 20, and they are (-1, -20), (-2, -10), and (-4, -5).
The prime factors of 20 are 2 x 2 x 5 = 22 x 5, obtained when the original number is divided by prime numbers. The total sum of factors of 20 are 1 + 2 + 4 + 5 + 20 = 32. Besides, you can find the factors of 20 using the division and multiplication methods. Learning multiplication tables for kids helps them calculate factors of 20 accurately. This encourages them to solve arithmetic problems confidently.
How to Find the Factors of 20?
To calculate the factors of 20, you need to divide the original number with the integers without leaving the remainder using the division method. Check out the following method given below.
20/1 = 20
20/2 = 10
20/4 = 5
20/5 = 4
20/10 = 2
20/20 = 1
Therefore, the factors of 20 are 1, 2, 4, 5, 10, and 20.
Pair Factors of 20
To find the pair factors of 20, you can multiply the two factors together to get the original number as the product. The pair of numbers multiplied together are called the pair factors of 20. These can be positive or negative numbers. Check out the following multiplication method to find the pair factors of 20.
1 x 20 = 20
2 x 10 = 20
4 x 5 = 20
5 x 4 = 20
10 x 2 = 20
20 x 1 = 20
Therefore, the pair factors of 20 are (1, 20), (2, 10), and (4, 5). Besides this, you can find the negative pair factors of 20 when you multiply two negative factors to get a positive result. Find the negative pair factors of 20 using the multiplication method given below.
-1 x -20 = 20
-2 x -10 = 20
-4 x -5 = 20
-5 x -4 = 20
-10 x -2 = 20
-20 x -1 = 20
Therefore, the negative pair factors of 20 are (-1, -20), (-2, -10), and (-4, -5).
Prime Factors of 20
The prime factors of 20 are the prime numbers. To find the prime factors of 20, you need to divide the original numbers with the least prime numbers. Then, you need to continue the division process until you get a quotient one. Check out the following steps to calculate the prime factors of 20 given below.
Step 1: Divide the original number 20 with the least prime number 2.
20/2 = 10
Step 2: Divide the number 10 with the prime number 2.
10/2 = 5
Step 3: Since the number 5 is not divisible by prime number 2, you can take prime number 5 to get a quotient one.
5/5 = 1
Therefore, the prime factors of 20 are 2 x 2 x 5 = 22 x 5.

Solved Examples on Factors of 20
Some of the solved examples on factors of 20 for kids are mentioned below:
Example 1: Find the common factors of 20 and 16.
Solution: Factors of 20 = 1, 2, 4, 5, 10, and 20.
Factors of 16 = 1, 2, 4, 8, and 16.
Therefore, the common factors of 20 and 16 are 1, 2 and 4.
Example 2: A baker baked 20 chocolate cupcakes for his customers. He distributed all the chocolate cupcakes equally to 10 customers. How many cupcakes did each customer get?
Solution: Number of chocolate cupcakes = 20
Number of customers = 10
Total number of chocolate cupcakes received by each customer = 20/10 = 2
Therefore, the total number of chocolate cupcakes received by each customer is 2.
