Is 6003 a prime number or a composite number?

Answer 1

Answer:

6003 is not a Prime number. It is a composite number.

Definition:

A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.

Explanation:

Any number for which the digits add to a number divisible by 3 is also divisible by 3, so it also has 3 as a factor. The sum of the digits of 6003 is 6 + 0 + 0 + 3 = 9, which is divisible by 3, which means 6003 is divisible by 3. Therefore, 6003 is a composite number.
