Check if numbers are coprime
Web2 numbers are co-prime if their SPFs are different. Preprocess all the SPFs and then store the SPFs of the numbers in the array in map. Now you will have the numbers whose SPFs is the same. Let ans = n* (n+1)/2 (n = size of the array), now you could iterate through the map and subtract the sizeofmap C 2 from the answer. WebSep 21, 2024 · The task is to check whether there exists at least one element in the given array that forms co-prime pair with all other elements of the array. If no such element exists then print No else print Yes. Examples: Input: arr [] = {2, 8, 4, 10, 6, 7} Output: Yes 7 is co-prime with all the other elements of the array Input: arr [] = {3, 6, 9, 12}

At least 8.4% of the numbers below X are coprime to it (for X of this size), so there are well over 10 300 numbers coprime to and smaller than X.
WebSep 1, 2024 · It can be observed that if GCD of any number, say x, with 1 is always 1, i.e. GCD (1, x) = 1. Since 1 will always be a factor of N, simply print any K factors of N with 1 as the coprime pairs. Below is the implementation of the above approach.
