ok im doing this other program on for loops for greatest common divisor, so the problem is i cant seem to display the common divisor of both numbers, so i seem to be having problems with the formula inside the for loop, so it doesn't work is there anything im missing

also another question how can i do to insert two numbers in one enter (insert two numbers just by spacing them?)Code:#include <math.h> #include <stdio.h> #include <stdlib.h> int main() { int g,n,m,i; printf("Give me two numbers separated by space (p>q): "); scanf("%d %d",&n,&m); for(i=0;i<=n%m;i++){ g=n%m; g=m%n; } printf("The GCD of %d and %d is %d ",n,m,g); getchar(); getchar(); }
