WebStep 1: First create a list of numbers from 2 to 100 as shown above. We leave the number 1 because all prime numbers are more than 1. Step 2: We start from the first number 2 in the list. We cross out every number which is a multiple of 2 except 2. For example, we cross 4, 6, 8, 10, 12, 14, 16, and so on up to 100. WebThe number of prime numbers decreases towards infinity. The higher the number is, the lower is the probability of finding it. For example, there are 25 prime numbers between 1 and 100, but only 21 prime numbers between 100 and 200, and 15 prime numbers between 200 and 300, and there are only 6 prime numbers between 10 000 and 10 100.
Web12 is not a prime number because it will divide by 1,2,3,4,6 and 12. This means that if you have 12 eggs, there are several different shaped boxes you can neatly fit them all into. 13 is a prime number because it will only divide exactly by 1 or 13. If you have 13 eggs, the only box they will neatly fit into has one row of 13 eggs.
