To determine if 1547 is a prime number or a composite number, we simply look at the factors for 1547.
If the factors of 1547 are only 1547 and 1, then we know that 1547 is a prime number. Otherwise, 1547 is a composite number.
To explain better, if 1547 is only divisible by 1 and 1547, then it is a prime number, and if 1547 is divisible by more than 1547 and 1, then it is a composite number.
The factors of 1547 are as follows:
1, 7, 13, 17, 91, 119, 221, 1547
Therefore, since 1547 is divisible by more than one and itself, the answer to the
question "Is 1547 prime or composite?" is highlighted in blue below.
