To determine if 1407 is a prime number or a composite number, we simply look at the factors for 1407.
If the factors of 1407 are only 1407 and 1, then we know that 1407 is a prime number. Otherwise, 1407 is a composite number.
To explain better, if 1407 is only divisible by 1 and 1407, then it is a prime number, and if 1407 is divisible by more than 1407 and 1, then it is a composite number.
The factors of 1407 are as follows:
1, 3, 7, 21, 67, 201, 469, 1407
Therefore, since 1407 is divisible by more than one and itself, the answer to the
question "Is 1407 prime or composite?" is highlighted in blue below.
