The better method is division.
For example: 49 and 91
A B temp
49 % 91 = 49
91 % 49 = 42
49 % 42 = 7
42 % 7 = 0
So the greatest common divisor is 7.
public class T {
public static void main(String[] args) {
int gcd = gcd(91, 49);
System.out.println(gcd);
}
public static int gcd(int a, int b) {
while(b != 0) {
int temp = a%b;
a = b;
b = temp;
}
return a;
}
}
