To determine if 2480 is a prime number or a composite number, we simply look at the factors for 2480.
If the factors of 2480 are only 2480 and 1, then we know that 2480 is a prime number. Otherwise, 2480 is a composite number.
To explain better, if 2480 is only divisible by 1 and 2480, then it is a prime number, and if 2480 is divisible by more than 2480 and 1, then it is a composite number.
The factors of 2480 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 31, 40, 62, 80, 124, 155, 248, 310, 496, 620, 1240, 2480
Therefore, since 2480 is divisible by more than one and itself, the answer to the
question "Is 2480 prime or composite?" is highlighted in blue below.
composite
Is 2481 prime or composite?
