To determine if 1406 is a prime number or a composite number, we simply look at the factors for 1406.
If the factors of 1406 are only 1406 and 1, then we know that 1406 is a prime number. Otherwise, 1406 is a composite number.
To explain better, if 1406 is only divisible by 1 and 1406, then it is a prime number, and if 1406 is divisible by more than 1406 and 1, then it is a composite number.
The factors of 1406 are as follows:
1, 2, 19, 37, 38, 74, 703, 1406
Therefore, since 1406 is divisible by more than one and itself, the answer to the
question "Is 1406 prime or composite?" is highlighted in blue below.
composite
Is 1407 prime or composite?
