In my Problem Solving class I was given this problem...

"Find two prime numbers that, if multiplied, would generate a 400-digit number."

My brain, calculator and every other working thing in my house cannot figure this out... is there anyone out there who can help me with this?

I think you are mistaking, 400 is a 3 digit number, not a 400 digit number.
