WebOct 31, 2024 · The number of positive integers, not greater than n, and relatively prime with n, equals to Euler’s totient function φ (n). In symbols we can state that. φ (n) = {a Î N: 1 ≤ a ≤ n, gcd (a, n) = 1} This function has the following properties: If p is prime, then φ § = p – 1 and φ (pa) = p a * (1 – 1/p) for any a.
WebMay 1, 1997 · There is a similar question, however, that has been proven. The weak Goldbach conjecture says that every odd whole number greater than 5 can be written as the sum of three primes. Again we can see that this is true for the first few odd numbers greater than 5: 7 = 3 + 2 + 2. 11 = 3 + 3 + 5. 13 = 3 + 5 + 5. 17 = 5 + 5 + 7.
