To determine if 3456 is a prime number or a composite number, we simply look at the factors for 3456.
If the factors of 3456 are only 3456 and 1, then we know that 3456 is a prime number. Otherwise, 3456 is a composite number.
To explain better, if 3456 is only divisible by 1 and 3456, then it is a prime number, and if 3456 is divisible by more than 3456 and 1, then it is a composite number.
The factors of 3456 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 64, 72, 96, 108, 128, 144, 192, 216, 288, 384, 432, 576, 864, 1152, 1728, 3456
Therefore, since 3456 is divisible by more than one and itself, the answer to the
question "Is 3456 prime or composite?" is highlighted in blue below.
