To determine if 1450 is a prime number or a composite number, we simply look at the factors for 1450.
If the factors of 1450 are only 1450 and 1, then we know that 1450 is a prime number. Otherwise, 1450 is a composite number.
To explain better, if 1450 is only divisible by 1 and 1450, then it is a prime number, and if 1450 is divisible by more than 1450 and 1, then it is a composite number.
The factors of 1450 are as follows:
1, 2, 5, 10, 25, 29, 50, 58, 145, 290, 725, 1450
Therefore, since 1450 is divisible by more than one and itself, the answer to the
question "Is 1450 prime or composite?" is highlighted in blue below.
composite
Is 1451 prime or composite?
