A Prime number is defined as a number thats divisible only by 1 and by itself.
So you have to check ...
Is 38 divisible by 1 ?
Yes, it is 38 x 1 = 38
It 38 divisible by itself ?
Again, yes : 1 x 38 = 38
Now comes the tricky part ....
You have to find out if 38 is divisible by something else than 1 and 38 ...
Theres a rule, for example, for numbers divisible by 3 : If the sum of the individual numbers is divisible by 3, the whole number is ... but 11 isn´t divisible by 3, so 38 also isn't.
Then, wait .... 38 is an even number, since 37 and 39 aren't.
Even numbers are divisible by 2.
38 / 2 = 19
19 is a prime number.
38 isn't.
