Asked by Kyle
How would I find the smallest three digit number that is divisible by exactly three different prime numbers? My friend says the answer is 2 - 3 - 17 but won't tell me how he got it. Any help would be much appreciated. Thank You.

Is 2-3-17 a three digit number?

the 3 smallest primes are 2,3,5.
So, 2*3*5=30 is the smallest number divisible by 3 primes.
But we want a 3-digit number
100 = 2^2 * 5 - nope only 2 primes
101 is prime - only one prime divisor
102 = 2*3*17 - we have a winner!

No, it's not a three digit number. I hardly listen to him anyway. So, What is the smallest three digit number that is divisible by exactly three different prime numbers and how do you get this? Thanks for any help you can give me.
