A prime number is a number that cannot be divisble except for 1 and itself.

However, 1 does not qualify, since it technically only 1 factor.

Now, the numbers \(2,3,5,7\) are all prime numbers.

However, \(4=2*2, 6=2*3, 8=2*4, 9=3*3, 10=2*5\)

So the answer is 2,3,5,7

Thanks! :)

This is pretty simple. NotThatSmart already showed one way. If you know your primes, you'll find 2, 3, 5, and 7 to be prime.
