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. 40 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 10. (All numbers that end in a 0 are divisible by 10.) Therefore, 40 is a composite number.
Prime number: A number which has only 1 and itself as factors.
Examples:
2 is a prime number. Because 2 = 1 x 2
3 is also a prime number. 3 = 1 x 3
Numbers which are not prime are called composite numbers.
They can be written as a product of numbers other than 1 and themselves.
40 has some more factors other than 1 and 40.
40 = 2 x 20 = 5 x 8
So, it's a composite number.
