C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int a,x=0,y=0;
	cin>>a;
	while(a%4==0){
		x++;
		a=a/4;
	}
	while(a%7==0){
		y++;
		a=a/7;
	}
	cout<<x<<" "<<y<<endl;
	return 0;	
}

Python :

# coding=utf-8
x = int ( input () )
i = 0
j = 0
while ( ( x % 4 ) == 0 ):
    x //= 4
    i += 1
while ( ( x % 7 ) == 0 ):
    x //= 7
    j += 1
print (i, j)
