i dont understand that game

We have to count in prime numbers.

97

101

198




In that way?

prime number: a number that has no factor except itself and 1.
for example 2, 3, 5, 7, 11,

198 its not a prime number because its "made" of a multiplication of other numbers
198 = 2 * 3 * 3 * 11

It is quite easy to find out if it is NOT a prime number.

1.) If the last digit is a 0, 2, 4, 6 or 8, it can be divided by 2.

2.) If you add all digits together and it is a number you can divide by 3.

Example: 12981

1+2+9+8+1= 21

You can divide 21 by 3.

3.) If the last digit is 0 or 5 it can be divided by 5.




So, first check the last number. It is no prime number if the last digit is 0, 2, 4, 5, 6 or 8. Then look whether it can be divided by 3.

If both does not work, it is a prime number.
