It works in the browser and is powered by alien technology from the future. It lets you generate as many primes as you need, starting from any value. This loop is broken when we have reached the breaking point of numbers to test. Last updated 1 week ago I often have to generate a sequence of prime numbers so I created this simple utility that does it for me. The outer loop works through all the numbers between 1 and 100. If the inner loop finds a divisor, the number is not prime, so it breaks out without printing anything, and if the testing gets as high as the square root of the number, we can assume that the number is prime. The inner while loop does the testing with each possible divisor. In the above code, we have two while loops. The following code prints a list of prime numbers between 1 and 100 (that is, numbers not divisible by something other than 1 or the number itself) using a while loop. Prime factorization involves finding the prime. Solution 1: Prime Number Program using While Loop Factors are important when working with fractions, as well as when trying to find patterns within numbers. These are different ways to print prime number between 1 to 100 in the PHP programming language. On the other hand, 18 is not a prime number because it is divisible by 2, 3, 6, 9 and the number itself. For example, 17 is a prime number because it is only divisible by 1 and 17. A prime number is a whole number greater than 1 whose only factors are 1 and itself, like -2, 3, 5, 7, 11 etc.
