Is 280 a prime number or a composite number?

Answer 1

Answer:

280 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 ending in 0, 2, 4, 6, or 8 is evenly divisible by 2, so it would have 2 as a factor. Also, any number ending in 0 or 5 is evenly divisible by 5, so it would have 5 as a factor. Thus, 280 is divisible by 2 and 5, so it is a composite number.
280 is a composite number because it has more than two factors

Answer 2

Composite!:D
