A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 105 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 105 is a composite number.

105 is not a prime number. You can readily see that 3 and 5 go into it, and 7 goes into it too. The number ends in 5, and 5 goes into any number ending in 0 or 5. The sum of the digits is 6, and when the sum of the digits is divisible by 3, then so is the original number.

As a product of its prime factors: 3*5*7 = 105
