To determine if 3906 is a prime number or a composite number, we simply look at the factors for 3906.
If the factors of 3906 are only 3906 and 1, then we know that 3906 is a prime number. Otherwise, 3906 is a composite number.
To explain better, if 3906 is only divisible by 1 and 3906, then it is a prime number, and if 3906 is divisible by more than 3906 and 1, then it is a composite number.
The factors of 3906 are as follows:
1, 2, 3, 6, 7, 9, 14, 18, 21, 31, 42, 62, 63, 93, 126, 186, 217, 279, 434, 558, 651, 1302, 1953, 3906
Therefore, since 3906 is divisible by more than one and itself, the answer to the
question "Is 3906 prime or composite?" is highlighted in blue below.
