To determine if 1250 is a prime number or a composite number, we simply look at the factors for 1250.
If the factors of 1250 are only 1250 and 1, then we know that 1250 is a prime number. Otherwise, 1250 is a composite number.
To explain better, if 1250 is only divisible by 1 and 1250, then it is a prime number, and if 1250 is divisible by more than 1250 and 1, then it is a composite number.
The factors of 1250 are as follows:
1, 2, 5, 10, 25, 50, 125, 250, 625, 1250
Therefore, since 1250 is divisible by more than one and itself, the answer to the
question "Is 1250 prime or composite?" is highlighted in blue below.
composite
Is 1251 prime or composite?
