To determine if 5640 is a prime number or a composite number, we simply look at the factors for 5640.
If the factors of 5640 are only 5640 and 1, then we know that 5640 is a prime number. Otherwise, 5640 is a composite number.
To explain better, if 5640 is only divisible by 1 and 5640, then it is a prime number, and if 5640 is divisible by more than 5640 and 1, then it is a composite number.
The factors of 5640 are as follows:
1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 47, 60, 94, 120, 141, 188, 235, 282, 376, 470, 564, 705, 940, 1128, 1410, 1880, 2820, 5640
Therefore, since 5640 is divisible by more than one and itself, the answer to the
question "Is 5640 prime or composite?" is highlighted in blue below.
composite
Is 5641 prime or composite?
