To determine if 7455 is a prime number or a composite number, we simply look at the factors for 7455.
If the factors of 7455 are only 7455 and 1, then we know that 7455 is a prime number. Otherwise, 7455 is a composite number.
To explain better, if 7455 is only divisible by 1 and 7455, then it is a prime number, and if 7455 is divisible by more than 7455 and 1, then it is a composite number.
The factors of 7455 are as follows:
1, 3, 5, 7, 15, 21, 35, 71, 105, 213, 355, 497, 1065, 1491, 2485, 7455
Therefore, since 7455 is divisible by more than one and itself, the answer to the
question "Is 7455 prime or composite?" is highlighted in blue below.
