To determine if 1086 is a prime number or a composite number, we simply look at the factors for 1086.
If the factors of 1086 are only 1086 and 1, then we know that 1086 is a prime number. Otherwise, 1086 is a composite number.
To explain better, if 1086 is only divisible by 1 and 1086, then it is a prime number, and if 1086 is divisible by more than 1086 and 1, then it is a composite number.
The factors of 1086 are as follows:
1, 2, 3, 6, 181, 362, 543, 1086
Therefore, since 1086 is divisible by more than one and itself, the answer to the
question "Is 1086 prime or composite?" is highlighted in blue below.
composite
Is 1087 prime or composite?
