The GCF is 20.
80 5X16; 32 2X16, so the greatest common divisor is 16.
GCD: 5 LCM: 880
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: 75
GCD: 4
GCD: 73
GCD stands for "greatest common divisor".
Euclid's Algorithm (http://www.cs.berkeley.edu/~vazirani/s99cs170/notes/lec3.pdf). the mod function (or %, as used here) is equal to the remainder of x/y. In this first case, 375 mod 275 = the remainder of 375/275, 375/275 is 1 r100 thus 375%275=100. gcd(375,275) => gcd(275,375%275) = gcd(275,100) =>gcd(100,275%100) = gcd(100,75) => gcd(75,100%75) = gcd(75,25) => gcd(25,75%25) = gcd(25,0) ===> gcd is 25.
The GCD of 500, 120 is 20.
The GCD is: 1The LCM is: 780
The Greatest Common Divisor (GCD) for 84 48 is 12
900 years and 78 years 900+78=978 978+12=1000 2000+1000=3000
