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 10.
The GCF is 5.
Answer: GCD=21 / LCM=420 A GCD/LCM calculator can be found in the "related links" section, below.
280 56 * 5 = 280 70 * 4 = 280
105 10 x 7 = 70 5 x 7 = 35 70 + 35 = 105
LCD(70, 105) = 210.
