To determine if 1586 is a prime number or a composite number, we simply look at the factors for 1586.
If the factors of 1586 are only 1586 and 1, then we know that 1586 is a prime number. Otherwise, 1586 is a composite number.
To explain better, if 1586 is only divisible by 1 and 1586, then it is a prime number, and if 1586 is divisible by more than 1586 and 1, then it is a composite number.
The factors of 1586 are as follows:
1, 2, 13, 26, 61, 122, 793, 1586
Therefore, since 1586 is divisible by more than one and itself, the answer to the
question "Is 1586 prime or composite?" is highlighted in blue below.
