To determine if 7520 is a prime number or a composite number, we simply look at the factors for 7520.
If the factors of 7520 are only 7520 and 1, then we know that 7520 is a prime number. Otherwise, 7520 is a composite number.
To explain better, if 7520 is only divisible by 1 and 7520, then it is a prime number, and if 7520 is divisible by more than 7520 and 1, then it is a composite number.
The factors of 7520 are as follows:
1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 47, 80, 94, 160, 188, 235, 376, 470, 752, 940, 1504, 1880, 3760, 7520
Therefore, since 7520 is divisible by more than one and itself, the answer to the
question "Is 7520 prime or composite?" is highlighted in blue below.
composite
Is 7521 prime or composite?
