Greatest Common Divisor (GCD) for 18 45 72 is 9.
The GCF is 9.
GCD: 9
GCD(45, 72) = 9 so the simplest form is (45/9) / (72/9) = 5/8
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.
GCD(27, 72) = 9
Prime factor each number. 18=2x3x3 45=3x3x5 72=2x2x2x3x3 Use each prime factor the number of times it was used the MOST in any one of the numbers. 2x2x2x3x3x5=360 The least common denominator of 18, 45, and 72 is 360.
The Greatest Common Divisor of 18, 45, 72 is 9.
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.
