To determine if 73 is a prime number or a composite number, we simply look at the factors for 73.
If the factors of 73 are only 73 and 1, then we know that 73 is a prime number. Otherwise, 73 is a composite number.
To explain better, if 73 is only divisible by 1 and 73, then it is a prime number, and if 73 is divisible by more than 73 and 1, then it is a composite number.
The factors of 73 are as follows:
1, 73
Therefore, since 73 is divisible by only one and itself, the answer to the
question "Is 73 prime or composite?" is highlighted in blue below.
prime
Is 74 prime or composite?
