123 is not a Prime number because it is divisible by 41 and 3. (123/41=3 and 123/3=41)

A prime number is any number that is only divisible by two factors, one and itself.

123 is a composite number because its factors are 1, 3, 41, and 123.

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. 123 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 1 + 2 + 3 = 6. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 123 is a composite number.
