Factors of 79 divides the original number, evenly or uniformly. It means there is no remainder left after division. These factors are also called divisors of the original number. Since 79 is a prime number, therefore, it will have only two factors.
79 is an odd number but not a perfect square. The multiplication table of 1 and 79 only has the value of 79.
How to Find the Factors of 79?
Factors of a number divide it into equal parts. Thus, the remainder should be zero.
| 79 ÷ 1 = 79 [Remainder = 0]
79 ÷ 79 = 1 [Remainder = 0] |
Therefore, there are only two factors of 79. They are 1 and 79.
Let us see if 79 is divisible by any other number.
79 ÷ 2 = 39.5
79 ÷ 5 = 15.8
79 ÷ 10 = 7.9
79 ÷ 35 = 2.25714285714
Since, 79 is not divisible by any other number, evenly, therefore apart from 1 and 79, there are no other possible factors.

Pair Factors of 79
The product of two natural numbers results in 79, to form a pair of factors. Thus, the possible pair factors of 79 are:
- 1 × 79 = 79
- 79 × 1 = 79
Therefore, the pair factors of 79 are (1, 79) or (79, 1).
If we consider pair factors in negative terms, then;
- -1 × -79 = 79
- -79 × -1 = 79
Therefore, the negative pair factors are (-1, -79) or (-79, -1).
Prime Factorisation of 79
79 is a prime number itself, therefore, prime factorisation of 79 is not possible. 79 is divisible by 79 only.
79 ÷ 79 = 1
| Prime factorisation of 79 = 79
Exponential form = 791 |
