What are Factors of 675?
Factors of 675 are pairs of those numbers whose products result in 675. These factors are either prime numbers or composite numbers.
How to Find the Factors of 675?
To find the factors of 675, we will have to find the list of numbers that would divide 675 without leaving any remainder.
- 675/225 = 3; therefore, 225 is a factor of 675 and 3 is also a factor of 675.
- 675/5 = 135; therefore, 5 is a factor of 675 and 135 is also a factor of 675.

Factors of 675 by Prime Factorization
- 675 ÷ 3 = 225
- 225 ÷ 3 = 75
- 75 ÷ 3 = 25
Further dividing 25 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 25 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 675 can be written as 33 × 52 where 3, 5 are prime.
Factors of 675 in Pairs
Pair factors of 675 are the pairs of numbers that when multiplied give the product 675. The factors of 675 in pairs are:
- 1 × 675 = (1, 675)
- 3 × 225 = (3, 225)
- 5 × 135 = (5, 135)
- 9 × 75 = (9, 75)
- 15 × 45 = (15, 45)
- 25 × 27 = (25, 27)
Negative pair factors of 675 are:
- -1 × -675 = (-1, -675)
- -3 × -225 = (-3, -225)
- -5 × -135 = (-5, -135)
- -9 × -75 = (-9, -75)
- -15 × -45 = (-15, -45)
- -25 × -27 = (-25, -27)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
Factors of 675 Solved Examples

Example 1: How many factors are there for 675?
Solution:
The factors of 675 are too many, therefore if we can find the prime factorization of 675, 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 675 = 33 × 52
Therefore, the total number of factors are (3 + 1) × (2 + 1) = 4 × 3 = 12 -
Example 2: Find the LCM and Greatest Common Divisor (GCD) of 675 and 312.
