Let's take one integer as x.

We know that, the consecutive one would obviously be x+1 and x+2

So the three numbers are x, x+1 and x+2.
Now, We know that they sum up to 156. Hence,
x+ x+1+ x+2=156
3x+3=156
3x=153
x=51
So the Consecutive integers will be 51, 52, 53 (x+1 and x+2)
Now that we have to find a number 'divisible' by 13. It is easy, We already know 52 is exactly divisibly by 13.
