49 (it is an arithmetic series that adds 5 then 7 then 9 then 11 then 13)
To find a number that goes into both 36 and 13, we can look for their greatest common divisor (GCD). The GCD of 36 and 13 is 1, since 13 is a prime number and does not divide 36. Therefore, the only integer that goes into both 36 and 13 is 1.
