GCD: 8

The GCF is 8.

Greatest Common Divisor (GCD) for 24 56 is 8.

The Greatest Common Divisor (GCD) for 56 72 is 8.

The GCF is 24.

It is: 72

gcd(a,b) = greatest common divisor (or factor, whatever) of a and b. For any set of number, a1, a2, a3, ..., you can use the Euclidean algorithm (http://en.wikipedia.org/wiki/Euclidean_algorithm) to get the gcd(a1, a2), and then again to get gcd(gcd(a1, a2), a3), etc. Often, though, you can eyeball it. So 24*3 = 72. Therefore, gcd(24, 72)=24. 24 does not divide 132, but 12 does (the next biggest factor of 24), so gcd(24, 72, 132)=12.

The least common multiple of 24 , 56 , 72 = 504

The greatest common factor of 24, 56 and 72 is 8.

The greatest common factor of 24 56 and 72 is 8.

56=2*2*2*724=2*2*2*32*2*2=8=GCD

The LCM is 8568

72/2 = 36

Euclid's algorithm is a popular algorithm to compute the GCD of two numbers. Algorithm: Gcd(a,b) = Gcd(b, a mod b), where a>=b and Gcd(a,0) = a Say we want to find the GCD of 72 and 105. 105 mod 72 = 33, so GCD(72,105) = GCD(33,72) 72 mod 33 = 6, so GCD(33,72) = GCD(6,33) 33 mod 6 = 3 so GCD(6,33) = GCD(3,6) 6 mod 3 = 0 so GCD(3,6) = GCD(0,3) = 3. So the GCD of 72 and 105 is 3.

The GCF is 8

Greatest Common Divisor (GCD) for 105 56 is 7.

The Greatest Common Divisor (GCD) for 56 84 is 28.

The Greatest Common Divisor (GCD) for 42 56 is 14.

GCD(24, 90) = 6

8

The GCF is 12.

since 14 = 14 x 1 and 56 = 14 x 4 the answer is 14, since it divides evenly into both and clearly nothing larger will.There is a clever algorithm that can help you work this out in the general case:GCD(14, 56) = GCD(14, 56 - 14) = GCD(14, 42)This step (subtract the smaller from the larger) relies on the fact that any number that divides both 14 and 56 also divides 56 - 14.Repeat this:GCD(14, 42) = GCD(14, 42 - 14) = GCD(14, 28)GCD(14, 28) = GCD(14, 28 - 14) = GCD(14, 14)which is clearly 14.This is called Euclid's Algorithm.
