To determine if 2172 is a prime number or a composite number, we simply look at the factors for 2172.
If the factors of 2172 are only 2172 and 1, then we know that 2172 is a prime number. Otherwise, 2172 is a composite number.
To explain better, if 2172 is only divisible by 1 and 2172, then it is a prime number, and if 2172 is divisible by more than 2172 and 1, then it is a composite number.
The factors of 2172 are as follows:
1, 2, 3, 4, 6, 12, 181, 362, 543, 724, 1086, 2172
Therefore, since 2172 is divisible by more than one and itself, the answer to the
question "Is 2172 prime or composite?" is highlighted in blue below.
composite
Is 2173 prime or composite?
