GCD Using while loop and if...else Statement



GCD Using while loop and if...else Statement

The HCF or GCD of two integers is the largest integer that can exactly divide both numbers (without a remainder).

#include <stdio.h>
int main()
{
    int j1, j2;
    
    printf("Enter two positive integers: ");
    scanf("%d %d",&j1,&j2);

    while(j1!=j2)
    {
        if(j1 > j2)
            j1 -= j2;
        else
            j2 -= j1;
    }
    printf("GCD = %d",j1);

    return 0;
}
