To determine if 1770 is a prime number or a composite number, we simply look at the factors for 1770.
If the factors of 1770 are only 1770 and 1, then we know that 1770 is a prime number. Otherwise, 1770 is a composite number.
To explain better, if 1770 is only divisible by 1 and 1770, then it is a prime number, and if 1770 is divisible by more than 1770 and 1, then it is a composite number.
The factors of 1770 are as follows:
1, 2, 3, 5, 6, 10, 15, 30, 59, 118, 177, 295, 354, 590, 885, 1770
Therefore, since 1770 is divisible by more than one and itself, the answer to the
question "Is 1770 prime or composite?" is highlighted in blue below.
composite
Is 1771 prime or composite?
