WebbThese are the primes which are less than the square root of 100, i.e. 10. In other words, it was only necessary to strike out the powers of 2, 3, 5 and 7 to complete the task for N=100. Can you see why this is? (Hint: The smallest composite number that is not divisible by 2, 3, 5 or 7 is 11 x 11 = 121). Writing an algorithm Webb1.) 200 = 100 x 2. 2.) 200 = (25 x 4) x 2. 3.) 200 = (5 x 5) x (2 x 2)) x 2. 200 = 5 x 5 x 2 x 2 x 2. So we can say a prime can only be a product of itself and 1. A non-prime can eventually be reduced to a product of 2 or more prime numbers. Therefore a non-prime is always divisible by a prime. Share.
