A prime number is only divisble by 1 and itself.

First, let's look at 1.

Even though it is divisible by 1, it only has one true factor, meaning it is not prime.

Next, we have 2. Two is only divisble by 1 and itself, so it qualifies.

Following this pattern, \(3=(3*1), 5=(5*1), 7=(7*1)\) are all prime.

However, \(4 = 2*2, 6=2*3, 8=2*4, 9=3*3, 10=2*5\)are all what we call composite.

Thus, we have \(2,3,5,7\) as our prime numbers.

Thanks! :)
