40 is a composite number. This is because composite numbers are any number that has more than two factors(one and itself). Therefore, since 2 and 4 to name a few are factors of 40 that makes it a composite number.

no Prime numbers are divisible only by themselves and 1. 40/10 = 4, for example, so no it is not prime.

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 2 because it is an even number. Therefore, 40 is a composite number.

A prime number is a whole number that cannot be divided evenly by any other positive whole number except 1 and itself. Can you think of a whole number you can divide 40 by other than 40 or 1? If so, it is not a prime number.

All of them except for 31 and 37 which are prime numbers

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 23 is also a prime number. 3 = 1 x 3Numbers 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 8So, it's a composite number.

Composite. It is 2 x 2 x 2 x 5.
