To determine if 6426 is a prime number or a composite number, we simply look at the factors for 6426.
If the factors of 6426 are only 6426 and 1, then we know that 6426 is a prime number. Otherwise, 6426 is a composite number.
To explain better, if 6426 is only divisible by 1 and 6426, then it is a prime number, and if 6426 is divisible by more than 6426 and 1, then it is a composite number.
The factors of 6426 are as follows:
1, 2, 3, 6, 7, 9, 14, 17, 18, 21, 27, 34, 42, 51, 54, 63, 102, 119, 126, 153, 189, 238, 306, 357, 378, 459, 714, 918, 1071, 2142, 3213, 6426
Therefore, since 6426 is divisible by more than one and itself, the answer to the
question "Is 6426 prime or composite?" is highlighted in blue below.
