What are Factors of 768?
Factors of 768 are pairs of those numbers whose products result in 768. These factors are either prime numbers or composite numbers.
How to Find the Factors of 768?
To find the factors of 768, we will have to find the list of numbers that would divide 768 without leaving any remainder.
- 768/192 = 4; therefore, 192 is a factor of 768 and 4 is also a factor of 768.
- 768/384 = 2; therefore, 384 is a factor of 768 and 2 is also a factor of 768.

Factors of 768 by Prime Factorization
- 768 ÷ 2 = 384
- 384 ÷ 2 = 192
- 192 ÷ 2 = 96
- 96 ÷ 2 = 48
- 48 ÷ 2 = 24
- 24 ÷ 2 = 12
- 12 ÷ 2 = 6
- 6 ÷ 2 = 3
Further dividing 3 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 3 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 768 can be written as 28 × 31 where 2, 3 are prime.

Example 1: How many factors are there for 768?
Solution:
The factors of 768 are too many, therefore if we can find the prime factorization of 768, 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 768 = 28 × 31
Therefore, the total number of factors are (8 + 1) × (1 + 1) = 9 × 2 = 18 -
