    400 digit answer to WHAT! Bah!
    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?
