Easy ways to find product of primes
WebStart dividing the number by the smallest prime number i.e., 2, followed by 3, 5, and so on to find the smallest prime factor of the number. Again, divide the quotient by the smallest prime number. Repeat the process, until the quotient becomes 1 after repeated division. Finally, represent the number as a product of all the prime factors. 2. WebNov 16, 2012 · All prime numbers either fall in multiples of 6n+1 or 6n-1 except for 2 and 3. Using this the search space could be considerably reduced for applying any sieve such as Atkins or Eratosthenes. Hence making it a slightly better form of finding primes.

WebAnswer: More generally, suppose n>1 and let n=\displaystyle \prod_{i=1}^r p_i^{e_i}, where the p_i’s are primes. In order for d \mid n to be coprime to \frac{n}{d}, we must have d=\displaystyle \prod_{i \in I \subseteq \{1,2,3,\ldots,r\}} p_i^{e_i}. Thus there are as many ordered pairs \left(d,\f...
