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 520 and 720 is 40
The greatest common factor can be found by factorizing all numbers and find the common factors. The product of these factors is the greatest common factor.128 = 2*2*2*2*2*2*21000 = 2*2*2*5*5*5The common factors are:2*2*2 Which means the greatest common factor is:2*2*2 = 8
36400 56*650 = 36400 65*560 = 36400
The GCF (Greatest Common Factor of 12, 14, and 20 is 212: 2 2 314: 2 720: 2 2 5
The GCF and LCM of 360 and 924 are 12 and 27720, respectively. 360 = 2 x 2 x 2 x 3 x 3 x 5, 924 = 2 x 2 x 3 x 7 x 11 HCF = 2 x 2 x 3, ie 12 LCM = 360 x 77, ie 27720
The Least Common Multiple (LCM) of 120 and 240 is 240. Because 240 is a multiple of 120, it is automatically the LCM of the pair. If you didn't notice that, you could also list the multiples of each number in the set, then choose the lowest one found in both lists and call it the least common multiple. Th multiples of 120 are 120, 240, 360, and so on. The multiples of 240 are 240, 480, 720, and so on. So the least common multiple of 120 and 240 is 24.
