Strike out the multiples of all primes less than or equal to the square root of n, then the numbers that … WebFigure: Go to the next unmarked number 5 (which is a prime number). Then, mark all multiples of 5. Start marking from number 5*5 because all multiples of 5 between 5 and 5*5=25 are already marked. Figure: Go to the next unmarked number 7 (which is a prime number). Then, mark all multiples of 7. bairrada mineola menu
