Is the number 391 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. 391 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 17. Therefore, 391 is a composite number.
Is 427 a prime number or a composite number?
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. 427 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 7. Therefore, 427 is a composite number.
Why is the number 1038 not a prime number?
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. 1038 has factors other than 1 and itself, so it cannot be a prime number. For example, it is divisible by 2 because it is an even number. Therefore, 1038 is a composite number.
