How to get the numbers which can divide all values in an array - JavaScript
We are required to write a JavaScript function that takes in an array of numbers and returns a number which can exactly divide all the numbers in the array.
Let’s say the following is our array −
const arr = [4, 6, 34, 76, 78, 44, 34, 26, 88, 76, 42];
Example
Following is the code −
const arr = [4, 6, 34, 76, 78, 44, 34, 26, 88, 76, 42]; const dividesAll = el => { const result = []; let num; for (num = Math.floor(el / 2); num > 1; num--){ if (el % num === 0) { result.push(num); } }; return result; }; const dividesArray = arr => { return arr.map(dividesAll).reduce((acc, val) => { return acc.filter(el => val.includes(el)); }); }; console.log(dividesArray(arr));
Output
This will produce the following output in console −
[ 2 ]
