To determine if 1572 is a prime number or a composite number, we simply look at the factors for 1572.
If the factors of 1572 are only 1572 and 1, then we know that 1572 is a prime number. Otherwise, 1572 is a composite number.
To explain better, if 1572 is only divisible by 1 and 1572, then it is a prime number, and if 1572 is divisible by more than 1572 and 1, then it is a composite number.
The factors of 1572 are as follows:
1, 2, 3, 4, 6, 12, 131, 262, 393, 524, 786, 1572
Therefore, since 1572 is divisible by more than one and itself, the answer to the
question "Is 1572 prime or composite?" is highlighted in blue below.
composite
