Factors of 135
The factors of 135 are integers that divide 135 completely, leaving no remainder. These factors can be positive or negative and usually come in pairs like (1, 135) and (-1, -135). Finding factors helps you understand how numbers are built and related to each other. You can discover the factors of 135 by testing smaller numbers or using prime factorization methods. Learning this concept is useful for topics such as multiples, least common multiples (LCM), and prime numbers. Here, you’ll find all factors, factor pairs, and the prime factorization of 135 explained simply.
What are the Factors of 135?
Factors of 135 are the numbers that divide it perfectly, leaving no remainder. The positive factors are 1, 3, 5, 9, 15, 27, 45 and 135, and if we include negatives, we get -1, -3, -5, -9, -15, -27, -45 and -135. Each factor fits into 135 an exact number of times. Understanding factors helps identify whether a number is simple like a prime, or made up of smaller parts like a composite. 135 is composite because it’s made from the multiplication of smaller whole numbers.
