The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 405 and 1125 is 45.
Oh, that's a happy little math question! To find the highest common factor of 120 and 405, we can first list the factors of each number. For 120, the factors are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. For 405, the factors are 1, 3, 5, 9, 15, 27, 45, 81, and 405. The highest common factor is 15, which is the largest number that both 120 and 405 can be divided by evenly.
Factor them. 2 x 3 x 3 = 18 3 x 3 x 3 x 3 x 5 = 405 Select the common factors. 3 x 3 = 9, the GCF
405 = (3)(3)(3)(3)(5)486 = (3)(3)(3)(3)(3)(2)(3)(3)(3)(3) = 81
The GCF is 135.
