Webb3 aug. 2024 · Prime numbers, which can only be divided by themselves and 1, are the building blocks of all whole numbers, yet no comprehensive formula for them has ever been found. The most famous is N 2 + N + 41, which generates primes for every value of N from 0 to 39 – which isn’t very impressive, given there’s an infinite number of primes. WebbThe Fundamental Theorem of Arithmetic states that for every integer n n greater than one, n > 1 n > 1, we can express it as a prime number or product of prime numbers. The theorem further asserts that each integer has a unique prime factorization thus it has a distinct combination or mix of prime factors.
