Went shopping today~

On top of the usual things, I bought these 2 books on an impulse:

I’m ok with math, but it’s not my strongest subject. xD

I’m going to post the first puzzle in the book. It made my brain hurt.

Two Russian mathematicians meet on a plane:

“I believe you have three sons, what are their ages today?” asks Ivan.

"Yes, I do have three sons. The product of their ages is 36, and the sum of their ages is exactly today’s date,” answers Igor.

“I’m sorry, Igor, but that doesn’t tell me the ages of your sons,” says Ivan after a minute or two.

“Oh I forgot to tell you. My youngest son has red hair.”

"Ah, now it’s clear. I now know exactly how old your sons are,” concludes Ivan.

How did Ivan work out the ages of the sons?
