To determine if 1740 is a prime number or a composite number, we simply look at the factors for 1740.
If the factors of 1740 are only 1740 and 1, then we know that 1740 is a prime number. Otherwise, 1740 is a composite number.
To explain better, if 1740 is only divisible by 1 and 1740, then it is a prime number, and if 1740 is divisible by more than 1740 and 1, then it is a composite number.
The factors of 1740 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 29, 30, 58, 60, 87, 116, 145, 174, 290, 348, 435, 580, 870, 1740
Therefore, since 1740 is divisible by more than one and itself, the answer to the
question "Is 1740 prime or composite?" is highlighted in blue below.
composite
Is 1741 prime or composite?
