Define flowchart and draw flowchart for GCD of two numbers?
pictorial representation of a program is called a flowchart
How do you write a C program to find the GCD of two given integers using non recursive functions?
Use the following function: int gcd (int a, int b) { while (b != 0) { a %= b; a ^= b ^= a ^= b; } return a; } Note that a ^= b ^= a ^= b is an efficient method of swapping two values.
What is pseudo code for GCD of two numbers?
public class GCD { public static void main(String[] args) { //Example how to use this method System.out.println(GCD(15,50)); } //find the greatest common divisor of two numbers public static int GCD(int a, int b){ if (b == 0) return a; return GCD(b, a % b); } } Hope this help to solve you problem.
How do you write a C program to find the GCD and LCM of two numbers using a switch statement?
The following function will return the GCD or LCM of two arguments (x and y) depending on the value of the fct argument (GCD or LCM). enum FUNC {GCD, LCM}; int gcd_or_lcm(FUNC fct, int x, int y) { int result = 0; switch (fct) { case (GCD): result = gcd (x, y); break; case (LCM): result = lcm (x, y); break; } return result; }

How do you write a C program to find the GCD and LCM of two numbers using a switch statement?
The following function will return the GCD or LCM of two arguments (x and y) depending on the value of the fct argument (GCD or LCM). enum FUNC {GCD, LCM}; int gcd_or_lcm(FUNC fct, int x, int y) { int result = 0; switch (fct) { case (GCD): result = gcd (x, y); break; case (LCM): result = lcm (x, y); break; } return result; }
The greatest common factor of 114 and 190?
The GCD is 38. You can find it with a calculator, using prime factorization with exponents, or using one of the many on-line GCD calculators.You can also list the factors of both numbers and find the largest one that they have in common.
