To determine if 3640 is a prime number or a composite number, we simply look at the factors for 3640.
If the factors of 3640 are only 3640 and 1, then we know that 3640 is a prime number. Otherwise, 3640 is a composite number.
To explain better, if 3640 is only divisible by 1 and 3640, then it is a prime number, and if 3640 is divisible by more than 3640 and 1, then it is a composite number.
The factors of 3640 are as follows:
1, 2, 4, 5, 7, 8, 10, 13, 14, 20, 26, 28, 35, 40, 52, 56, 65, 70, 91, 104, 130, 140, 182, 260, 280, 364, 455, 520, 728, 910, 1820, 3640
Therefore, since 3640 is divisible by more than one and itself, the answer to the
question "Is 3640 prime or composite?" is highlighted in blue below.
composite
Is 3641 prime or composite?
