To determine if 4640 is a prime number or a composite number, we simply look at the factors for 4640.
If the factors of 4640 are only 4640 and 1, then we know that 4640 is a prime number. Otherwise, 4640 is a composite number.
To explain better, if 4640 is only divisible by 1 and 4640, then it is a prime number, and if 4640 is divisible by more than 4640 and 1, then it is a composite number.
The factors of 4640 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 29, 32, 40, 58, 80, 116, 145, 160, 232, 290, 464, 580, 928, 1160, 2320, 4640
Therefore, since 4640 is divisible by more than one and itself, the answer to the
question "Is 4640 prime or composite?" is highlighted in blue below.
composite
Is 4641 prime or composite?
