The GCF is 12.
The GCF is 15.
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 180 and 220 is 20
The greatest common factor (GCF) of 78 and 780 is 78. Since 78 is a factor of 780, it is automatically the GCF.
36400 56*650 = 36400 65*560 = 36400
The factors of 780 are 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780 For them to be common, they need to be compared to another set of factors.
The common factors are: 1, 3, 13, 39
The answer is 780 780/65=12 780/26=30 780/12=65 780 is the lowest common multiple that each of the numbers all have in common.
