Factors of 900

The factors of 900 are integers that divide 900 completely, leaving no remainder. These factors can be positive or negative and usually come in pairs like (1, 900) and (-1, -900). Finding factors helps you understand how numbers are built and related to each other. You can discover the factors of 900 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 900 explained simply.

What are the Factors of 900?

Factors of 900 are the numbers that divide it perfectly, leaving no remainder. The positive factors are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450 and 900, and if we include negatives, we get -1, -2, -3, -4, -5, -6, -9, -10, -12, -15, -18, -20, -25, -30, -36, -45, -50, -60, -75, -90, -100, -150, -180, -225, -300, -450 and -900. Each factor fits into 900 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. 900 is composite because it’s made from the multiplication of smaller whole numbers.
