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 54, 175, and 560 is 1.
560
36400 56*650 = 36400 65*560 = 36400
16: 1, 2, 4, 8, 16 35: 1, 5, 7, 35 The GCF of 16 and 35 is 1.
Ah, the greatest common factor of 128 and 256 is 128. You see, the greatest common factor is the largest number that divides evenly into both numbers, and in this case, 128 is the biggest number that fits that description. Just imagine those numbers as happy little friends, sharing their common factor joyfully.
You need at least two numbers to find a GCF.
HCF is the highest common factor of two or more numbers. HCf of 260 and 560 is 20.
The GCF of 49 and 560 is 7.The factors of 49 are 1 x 49 and 7 x 7.The factors of 560 are 1 x 560, 2 x 280, 4 x 140, 5 x 112, 7 x 80, 8 x 70, 10 x 56, 14 x 40, 16 x 35, and 20 x 28.The only common factors are 1 and 7, so the greatest common factor of 49 and 560 is 7.
The GCF of 25, 60, and 75 is 5.The factors of 25 are: 1, 5, 25The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60The factors of 75 are: 1, 3, 5, 15, 25, 75The common factors are: 1, 5The Greatest Common Factor (GCF) is: 5

LCM(16, 28, 40) = 560.There is really no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
