Method to find prime numbers
Consider the arrangement of numbers from 1 to 36 into six columns. Extending this pattern, we arrange numbers up to 102 in the same manner.
Observations:
- The numbers in the columns corresponding to 2, 3, 4, and 6 are mostly composite, except for the prime numbers 2 and 3.
- This implies that all other prime numbers will be found in the columns corresponding to 1 and 5.
Thus, this systematic arrangement provides an efficient way to identify prime numbers by focusing only on specific columns. Based on this method, continue identifying prime numbers up to 102.
