The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 and 23, and we have a prime number chart if you need more. If we can make it by multiplying other whole numbers it is a Composite Number. 2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so on...

If any of them go into your number evenly, it's composite. With 91 you try 2, 3, and 5; they don't go in evenly (they leave a remainder); but 91 ÷ 7 = 13. This means 91 = 7 × 13, so it's not a prime after all.

The number 8 is not prime because it has four factors: 1, 2, 4 and 8. The number 1 is not a prime number because it only has one factor (itself).

Is 99 a prime number? For 99, the answer is: No, 99 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 99) is as follows: 1, 3, 9, 11, 33, 99. For 99 to be a prime number, it would have been required that 99 has only two divisors, i.e., itself and 1.

A prime number is a natural number, greater than one, that can only be divided by 1 and itself. The number 26 can be evenly divided by 1, 2, 13 and 26, with no remainder. Since 26 cannot be divided by just 1 and 26, it is not a prime number.
