To determine if 7500 is a prime number or a composite number, we simply look at the factors for 7500.
If the factors of 7500 are only 7500 and 1, then we know that 7500 is a prime number. Otherwise, 7500 is a composite number.
To explain better, if 7500 is only divisible by 1 and 7500, then it is a prime number, and if 7500 is divisible by more than 7500 and 1, then it is a composite number.
The factors of 7500 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 125, 150, 250, 300, 375, 500, 625, 750, 1250, 1500, 1875, 2500, 3750, 7500
Therefore, since 7500 is divisible by more than one and itself, the answer to the
question "Is 7500 prime or composite?" is highlighted in blue below.
composite
