Number Theory

Now, first, we can immediately tell something about both numbers. 

Adding the digits of the numbers together, we get that

$7+0+2+9+3+6=27$ and $8+4+1+1+3+1=18$

This means that both integers are divisble by 9. 

We have

$702936/9=78104$

$841131/9=93459$

However, now note that

The factors of 93459 are $1, 3, 31153, 93459$

The factors of 78104 are $1, 2, 4, 8, 13, 26, 52, 104, 751, 1502, 3004, 6008, 9763, 19526, 39052, 78104$

They share no common factors other than 1. 

Thus, our final answer is just $9*1=9$

so our answer is 9. 

Thanks! :)
