Jul 26, 2019 · In this section, we will see how we can get the largest prime factor of a number in an efficient way. There is a number say n = 1092, we have to get the largest prime factor of this. The prime factors of 1092 are 2, 2, 3, 7, 13. So the largest is 13. To solve this problem, we have to follow this rule −. When the number is divisible by 2, then store 2 as largest, and divide the number by 2 repeatedly.

Algorithm to find Largest prime factor of a number · My approach was: (1) divide large, possible number by 2; (2) check if the large number ...

13 is the largest (and the only … except for 2) prime factor. As noted in the comment 2 is a prime number, since it is divisible only by itself or 1 ...

We want to compare the greatest prime factors between the two quantities, which tells us that it likely tests our Integers math skill.

Aug 19, 2019 · You will find all the prime factors of a number and find the largest of them. The prime factors 124 = 2 x 2 x 31. and 31 is the largest of them.

Prime Factor− In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly. The process of finding these numbers is called integer factorization, or prime factorization.Input: n = 124 Output: 31 is the largest prime factor!

So, if you have found all factor less than √N and divide N by all the factors, the remaining number is a prime number and is the largest prime factor. With this, you can solve this problem efficiently.

The approach is simple, just factorise the given number by dividing it with the divisor of a number and keep updating the maximum prime factor.
