To determine if 4242 is a prime number or a composite number, we simply look at the factors for 4242.
If the factors of 4242 are only 4242 and 1, then we know that 4242 is a prime number. Otherwise, 4242 is a composite number.
To explain better, if 4242 is only divisible by 1 and 4242, then it is a prime number, and if 4242 is divisible by more than 4242 and 1, then it is a composite number.
The factors of 4242 are as follows:
1, 2, 3, 6, 7, 14, 21, 42, 101, 202, 303, 606, 707, 1414, 2121, 4242
Therefore, since 4242 is divisible by more than one and itself, the answer to the
question "Is 4242 prime or composite?" is highlighted in blue below.
