Gcd euclidean algorithm c++
WebThe Euclidean Algorithm for finding GCD (A,B) is as follows: If A = 0 then GCD (A,B)=B, since the GCD (0,B)=B, and we can stop. If B = 0 then GCD (A,B)=A, since the GCD (A,0)=A, and we can stop. Write A in quotient … WebSep 29, 2024 · Here, in this section we will discuss GCD of two numbers in C++. GCD (Greatest Common Divisor) of two numbers is the largest number that divides both numbers. Example : The GCD of 45 and 30 will be : Factors of 45 are 3 X 3 X 5. Factors of 30 are 2 X 3 X 5. Common factors of 45 and 30 are : 3 X 5 , So the required GCD will be …
