The GCF is 9.

GCD: 9

GCD(45, 72) = 9 so the simplest form is (45/9) / (72/9) = 5/8

It is: 72

The GCF of 18, 45, and 72 is 9.

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.

If you have two numbers m and n and their gcd (or gcf), g then their LCM = m*n/g so LCM = 72*252/36 = 2*252 = 504.

The greatest common factor of the numbers 27, 45 and 72 is 9.

Note that: 72 = 9 * 8 Then, since 72 contains the factor 9, one of the given numbers, the gcd is 9.

It is: 9
