What are Factors of 816?
Factors of 816 are pairs of those numbers whose products result in 816. These factors are either prime numbers or composite numbers.
How to Find the Factors of 816?
To find the factors of 816, we will have to find the list of numbers that would divide 816 without leaving any remainder.
- 816/34 = 24; therefore, 34 is a factor of 816 and 24 is also a factor of 816.
- 816/2 = 408; therefore, 2 is a factor of 816 and 408 is also a factor of 816.

Factors of 816 by Prime Factorization
- 816 ÷ 2 = 408
- 408 ÷ 2 = 204
- 204 ÷ 2 = 102
- 102 ÷ 2 = 51
Further dividing 51 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 51 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 816 can be written as 24 × 31 × 171 where 2, 3, 17 are prime.

Example 1: How many factors are there for 816?
Solution:
The factors of 816 are too many, therefore if we can find the prime factorization of 816, 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 816 = 24 × 31 × 171
Therefore, the total number of factors are (4 + 1) × (1 + 1) × (1 + 1) = 5 × 2 × 2 = 20 -
