Table listing the factors of 144
 

It is easy to find the factors of a number. We can identify the factors of 144 with the help of the methods mentioned below:

• Multiplication Method

• Division Method

• Prime Factor and Prime Factorization

• Factor Tree
   

The multiplication method finds the pair of numbers that when multiplied gives 144 as their product.

Step 1: Find all the numbers whose product is 144. 

Step 2: These numbers are the factors of 144

Step 3:Group these numbers as pairs.

Here’s a list of paired numbers whose product is 144:

1 × 144 =144

2 × 72 = 144

3 × 48 = 144

4 × 36 = 144

6 × 24 = 144

8 × 18 = 144

9 × 16 = 144

12 × 12 = 144

For the division method, the process of division will go on until the remainder becomes zero.

Step 1: 1 will always be a factor of any number because we can divide any number by 1.  Example: 144÷1 = 144. 

Step 2: Move to the next integer and continue this process until you can’t divide 144 anymore.

Overview of Factors of 144 using the division method

Prime factors are the prime numbers, having 1 and the numbers themselves as factors. Prime factorization is breaking down the number into its prime factors and expressing their product in exponential form.

Prime factors of 144: 2, 3

To find the prime factors of 144

Step 1: Divide 144 with the prime number 2
