To determine if 7480 is a prime number or a composite number, we simply look at the factors for 7480.
If the factors of 7480 are only 7480 and 1, then we know that 7480 is a prime number. Otherwise, 7480 is a composite number.
To explain better, if 7480 is only divisible by 1 and 7480, then it is a prime number, and if 7480 is divisible by more than 7480 and 1, then it is a composite number.
The factors of 7480 are as follows:
1, 2, 4, 5, 8, 10, 11, 17, 20, 22, 34, 40, 44, 55, 68, 85, 88, 110, 136, 170, 187, 220, 340, 374, 440, 680, 748, 935, 1496, 1870, 3740, 7480
Therefore, since 7480 is divisible by more than one and itself, the answer to the
question "Is 7480 prime or composite?" is highlighted in blue below.
