To determine if 1972 is a prime number or a composite number, we simply look at the factors for 1972.
If the factors of 1972 are only 1972 and 1, then we know that 1972 is a prime number. Otherwise, 1972 is a composite number.
To explain better, if 1972 is only divisible by 1 and 1972, then it is a prime number, and if 1972 is divisible by more than 1972 and 1, then it is a composite number.
The factors of 1972 are as follows:
1, 2, 4, 17, 29, 34, 58, 68, 116, 493, 986, 1972
Therefore, since 1972 is divisible by more than one and itself, the answer to the
question "Is 1972 prime or composite?" is highlighted in blue below.
composite
Is 1973 prime or composite?
