To determine if 7400 is a prime number or a composite number, we simply look at the factors for 7400.
If the factors of 7400 are only 7400 and 1, then we know that 7400 is a prime number. Otherwise, 7400 is a composite number.
To explain better, if 7400 is only divisible by 1 and 7400, then it is a prime number, and if 7400 is divisible by more than 7400 and 1, then it is a composite number.
The factors of 7400 are as follows:
1, 2, 4, 5, 8, 10, 20, 25, 37, 40, 50, 74, 100, 148, 185, 200, 296, 370, 740, 925, 1480, 1850, 3700, 7400
Therefore, since 7400 is divisible by more than one and itself, the answer to the
question "Is 7400 prime or composite?" is highlighted in blue below.
composite
Is 7401 prime or composite?
