My age is a product of (exactly) two prime numbers. Also, the same was true before my last birthday and will be true after my upcoming birthday.

How old am I?

(You can assume that my age is within a reasonable human lifespan, measured in years. This gives more than one possible age. Find all of them.)

you are 34 years old :)

34 = 17x2

Before your last birthday you were 33 ( = 11 x 3)

and after your next birthday you will be 35 (= 7 x 5) – Katie Gardner · 2 years, 2 months ago
