To determine if 6408 is a prime number or a composite number, we simply look at the factors for 6408.
If the factors of 6408 are only 6408 and 1, then we know that 6408 is a prime number. Otherwise, 6408 is a composite number.
To explain better, if 6408 is only divisible by 1 and 6408, then it is a prime number, and if 6408 is divisible by more than 6408 and 1, then it is a composite number.
The factors of 6408 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72, 89, 178, 267, 356, 534, 712, 801, 1068, 1602, 2136, 3204, 6408
Therefore, since 6408 is divisible by more than one and itself, the answer to the
question "Is 6408 prime or composite?" is highlighted in blue below.
