How to find the least prime factor of a number?
Prerequisites: Sieve of Eratosthenes, Least prime factor of numbers till n. Recommended: Please try your approach on {IDE} first, before moving on to the solution. Key Concept: Our idea is to store the Smallest Prime Factor (SPF) for every number.
Which is the first factor of a natural number?
Every natural number greater than 1 has at least one prime factor. Also, the first factor f found must be a prime number, because a factor of a factor is itself a factor. If g is a factor of f smaller than f, and f is a factor of n, then g is a factor of n and it would have been found first.
Are there any numbers with no prime factor above 5?
A regular number has no prime factor above 5 (so it is 5-smooth). The first: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16 (sequence A051037 in the OEIS). A k – powersmooth number has all pm ≤ k where p is a prime factor with multiplicity m.
