What is the smallest number that has 5 different prime factors?
To calculate this interesting number you need to use the five smallest prime numbers. A prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
