Faktor angka
/*
JavaScript program for factors of a number by lolman_ks.
Same logic can be used to build this program in other languages.
*/
/*
Logic: Divide the number by every number less than half of the number and
check for exact divisibility.
Add to the factors array if exactly divisible.
*/
function factors(number){
var factor_array = []; //Create an empty array.
//Run a loop to check divisibility.
for(let i = 0;i < Math.ceil(number / 2);++i){
if(number % i == 0) factor_array.push(i); //Check for exact divisibility.
}
factor_array.push(number); //Add the number itself in the factor array.
return factor_array;
}
//Program for perfect number can also be built using the above function.
