To determine if 7242 is a prime number or a composite number, we simply look at the factors for 7242.
If the factors of 7242 are only 7242 and 1, then we know that 7242 is a prime number. Otherwise, 7242 is a composite number.
To explain better, if 7242 is only divisible by 1 and 7242, then it is a prime number, and if 7242 is divisible by more than 7242 and 1, then it is a composite number.
The factors of 7242 are as follows:
1, 2, 3, 6, 17, 34, 51, 71, 102, 142, 213, 426, 1207, 2414, 3621, 7242
Therefore, since 7242 is divisible by more than one and itself, the answer to the
question "Is 7242 prime or composite?" is highlighted in blue below.
