Write out the numbers 1 to 50 in 5 rows. Cross out 1. Start at 2 and cross out multiples of 2. That would eliminate all the rest of the even numbers. Go to the next uncrossed-out number (3) and cross out all of its multiples. Some of them will already be crossed out. You can stop by the time you get to eight. All of the uncrossed-out numbers are prime.
If you mean, using the Sieve of Eratosthenes, you only need to check off prime numbers that are lower than the square root of the highest number - in this case, the square root of 100, which is 10 - so the prime numbers you need to check off are 2, 3, 5, 7.
The Sieve of Eratosthenes is a method used to find all prime numbers up to a given limit. The square root is utilized in this sieve because if a number has a factor larger than its square root, then it must also have a corresponding factor smaller than its square root. Therefore, by only checking numbers up to the square root of the given limit, we can effectively identify all the prime numbers.

999,999,999 numbers less than 1,000,000,000.
The natural numbers are the counting numbers. Therefore, the natural numbers less than 31 are the numbers from 1 to 30.
To find prime numbers less than 100, the sieve of eratosthenes filters out 1 and all multiples of 2, 3, 5, and 7. All remaining numbers less than 100 are primes.

Numbers less than zero are "negative numbers".
You can extend it indefinitely, depending on your patience!

The prime numbers that are less than 14 are: 2,3,5,7,11,13.
There are 35 prime numbers less than 150.
999,999,999 numbers less than 1,000,000,000.
Many numbers are less than 3.25. Less means that the numbers are smaller.
