For 125, the answer is: No, 125 is not a prime number. The list of all positive divisors (i.e., the list of all integers that divide 125) is as follows: 1, 5, 25, 125. To be 125 a prime number, it would have been required that 125 has only two divisors, i.e., itself and 1. As a consequence:
How to find the prime numbers from 1 to 1000?
To find the prime numbers from 1 to 1000, we need to check if the number is a natural number and has no positive divisor other than 1 and itself. We do not consider 1 as a prime number, as it has only one factor but other prime numbers have two factors. For example, 5 is a prime number, because it has only two factors, 1 and 5, such as; 5 = 1 x 5
