## What are the factors of 135?

If the multiplication of two positive integers is equal to 135 then those two integers are factors of 135.
Example: 15 multiplied by 9 is equal to 135 (15*9=135) so 15 and 9 are factors of 135.
If we divide 135 by one of its factors we find an integer quotient that is another factor of 135, the remainder of that division is equal to zero.
Example: 135 divided by 3 is equal to 45, the remainder of the division is equal to zero, 3 and 45 are factors of 135.
135 has 8 factors, here are the 8 factors of 135: 1; 3; 5; 9; 15; 27; 45; 135.
Here are all the products of two integers that are equal to 135: 1*135=135; 3*45=135; 5*27=135; 9*15=135.
Remark:135 is not a prime number because 135 has more than two factors then 135 is a composite number.
The prime factors of 135 are: 5 and 3.
The prime factorization of 135 is: 3^3*5.
