To determine if 1490 is a prime number or a composite number, we simply look at the factors for 1490.
If the factors of 1490 are only 1490 and 1, then we know that 1490 is a prime number. Otherwise, 1490 is a composite number.
To explain better, if 1490 is only divisible by 1 and 1490, then it is a prime number, and if 1490 is divisible by more than 1490 and 1, then it is a composite number.
The factors of 1490 are as follows:
1, 2, 5, 10, 149, 298, 745, 1490
Therefore, since 1490 is divisible by more than one and itself, the answer to the
question "Is 1490 prime or composite?" is highlighted in blue below.
