Question

I have in mind three consecutive
two-digit numbers and I have
calculated their sum and their
product. I have then listed those
positive integers which divide exactly
into both the sum and the product.
It turns out that there are just six
numbers in that list and that the
sum of the six numbers is odd. What
are the three consecutive two-digit
numbers?​
