## What Are the Factors of 144?

Factors of a number are the numbers that divide the given number exactly with no remainder. Factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. So,144 is a composite number as it has factors other than 1 and itself.

## How to Calculate the Factors of 144?

We can use different methods like divisibility test, prime factorization, and the upside-down division method to calculate the factors of 144. In prime factorization, we express 144 as a product of its prime factors and in the division method we divide the number by whole numbers or integers. Let us see what all numbers divide 144 exactly without a remainder.

### Prime Factorization by Division Method

The upside-down division got its name so because the division symbol is flipped upside down.

STEP 3: We then find the prime factors of the obtained quotient. Repeat Step 1 and Step 2 till we get the prime number as a quotient. In the last step, 9 is the quotient (9 ÷ 3= 3) 3 is the quotient, so we stop the process here.**Therefore, prime factorization of 144 = 2 × 2 × 2 × 2 × 3 × 3.**

**2 and 3 are prime factors of 14.**
