To determine if 3680 is a prime number or a composite number, we simply look at the factors for 3680.
If the factors of 3680 are only 3680 and 1, then we know that 3680 is a prime number. Otherwise, 3680 is a composite number.
To explain better, if 3680 is only divisible by 1 and 3680, then it is a prime number, and if 3680 is divisible by more than 3680 and 1, then it is a composite number.
The factors of 3680 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 23, 32, 40, 46, 80, 92, 115, 160, 184, 230, 368, 460, 736, 920, 1840, 3680
Therefore, since 3680 is divisible by more than one and itself, the answer to the
question "Is 3680 prime or composite?" is highlighted in blue below.
composite
Is 3681 prime or composite?
