To determine if 975 is a prime number or a composite number, we simply look at the factors for 975.
If the factors of 975 are only 975 and 1, then we know that 975 is a prime number. Otherwise, 975 is a composite number.
To explain better, if 975 is only divisible by 1 and 975, then it is a prime number, and if 975 is divisible by more than 975 and 1, then it is a composite number.
The factors of 975 are as follows:
1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
Therefore, since 975 is divisible by more than one and itself, the answer to the
question "Is 975 prime or composite?" is highlighted in blue below.
composite
Is 976 prime or composite?
