To determine if 1950 is a prime number or a composite number, we simply look at the factors for 1950.
If the factors of 1950 are only 1950 and 1, then we know that 1950 is a prime number. Otherwise, 1950 is a composite number.
To explain better, if 1950 is only divisible by 1 and 1950, then it is a prime number, and if 1950 is divisible by more than 1950 and 1, then it is a composite number.
The factors of 1950 are as follows:
1, 2, 3, 5, 6, 10, 13, 15, 25, 26, 30, 39, 50, 65, 75, 78, 130, 150, 195, 325, 390, 650, 975, 1950
Therefore, since 1950 is divisible by more than one and itself, the answer to the
question "Is 1950 prime or composite?" is highlighted in blue below.
composite
Is 1951 prime or composite?
