Prime Numbersని ఎలా లెక్కించాలి

Prime Numbers అంటే ఏమిటి?

A prime number is a whole number greater than 1 that has exactly two factors: 1 and itself. Primes are the "atoms" of arithmetic — every integer greater than 1 can be written as a unique product of primes (fundamental theorem of arithmetic).
