If the least prime factor of a is 3
Web14 okt. 2016 · The least prime factor of an integer N is the smallest prime number that divides it. The least prime factor of all even numbers is 2. A prime number is its own least prime factor (as well as its own greatest prime factor). Note : 1 needs to be printed for 1. Input: N = 6 Output: 1 2 3 2 5 2 Web18 jul. 2012 · Expert Answer Since, 3 is the least prime factor of 'a' therefore the number 'a' must be odd (because if the number would have been even, then the least prime factor will definitely be '2') So, a is odd. Similarly , b is also odd. Hence a + b is even (that is, a multiple of 2) Thus the least prime factor of 'a + b' is 2.

The prime factorization of a positive integer is a list of the integer's prime factors, together with their multiplicities; the process of determining these factors is called integer factorization.
WebThe theorem you have stated is incorrect: 25 has no prime factor less than 5, and 3 has no prime factor less than 1.732; however, it is true that every composite number has a prime factor less than or equal to its square root.

Web30 mrt. 2024 · Now, if we check on number ‘a’, the least prime factor is 3. Here 3 is an odd number and it can divide both even and odd numbers. But ‘a’ cannot be an even number as all even numbers are divisible by ‘2’ which is prime number and less than ‘3’. So, ‘a’ is an odd number. We know an odd number can be represented as 2 p − 1 ( p ≥ 1). WebThis theorem states that natural numbers greater than 1 are either prime, or can be factored as a product of prime numbers. As an example, the number 60 can be factored into a product of prime numbers as follows: 60 = 5 × 3 × 2 × 2 As can be seen from the example above, there are no composite numbers in the factorization.
