To determine if 3580 is a prime number or a composite number, we simply look at the factors for 3580.
If the factors of 3580 are only 3580 and 1, then we know that 3580 is a prime number. Otherwise, 3580 is a composite number.
To explain better, if 3580 is only divisible by 1 and 3580, then it is a prime number, and if 3580 is divisible by more than 3580 and 1, then it is a composite number.
The factors of 3580 are as follows:
1, 2, 4, 5, 10, 20, 179, 358, 716, 895, 1790, 3580
Therefore, since 3580 is divisible by more than one and itself, the answer to the
question "Is 3580 prime or composite?" is highlighted in blue below.
composite
Is 3581 prime or composite?
