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.
No because 40 is a composite number with more than two factors.
It is a composite number because it has more than two factors
40 is composite.
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.
42
composite because it has more than two factors.
It is a composite number because it's an even number and it has more than two factors
no Prime numbers are divisible only by themselves and 1. 40/10 = 4, for example, so no it is not prime.
no even number greater than 2 is prime so it is composite40 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.
It is not a prime number, it is a composite number.
It is prime
86 is not a prime number, so is a composite.
