What are Factors of 756?
Factors of 756 are pairs of those numbers whose products result in 756. These factors are either prime numbers or composite numbers.
How to Find the Factors of 756?
To find the factors of 756, we will have to find the list of numbers that would divide 756 without leaving any remainder.
- 756/3 = 252; therefore, 3 is a factor of 756 and 252 is also a factor of 756.
- 756/9 = 84; therefore, 9 is a factor of 756 and 84 is also a factor of 756.

Factors of 756 by Prime Factorization
- 756 ÷ 2 = 378
- 378 ÷ 2 = 189
Further dividing 189 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 189 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 756 can be written as 22 × 33 × 71 where 2, 3, 7 are prime.

Example 1: How many factors are there for 756?
Solution:
The factors of 756 are too many, therefore if we can find the prime factorization of 756, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 756 = 22 × 33 × 71
Therefore, the total number of factors are (2 + 1) × (3 + 1) × (1 + 1) = 3 × 4 × 2 = 24 -
