    Are you asking us to say whether or not they're prime numbers?
    Or to make up those numbers via prime number multiples?

    That's a prime number finder. For the numbers that aren't prime numbers, it will list the factors. When the factors aren't prime numbers, you can just put that number into the prime number finder to see those factors, and continue down until you get all the prime numbers that make that original number.

    I'll do the first one for you.

    93 - Put that into the program. Factors are 1,3,31,93.
    3 x 31 = 93, so prime numbers = 1,3,31.

    hehe I remember this in 7th grade, I wrote a program in Qbasic to figure out all the factors of a number i input. For some reason, the program couldnt handle over the number 9000
