# Find the Least Common Multiple

Tell us what’s happening:
So I have tried to create this ‘multiple’ function which calls itself using the `every() method` to check until the number is a multiple of all given numbers. I have kinda confused myself in the process, I feel very close yet also feel so far. I don’t know if my train of thought is correct. Any pointers will be of great help. thank you.

function smallestCommons(arr) {
const arr1 = arr.sort((a,b)=>a-b)
//console.log(arr)
const [a,b] = arr1;
//console.log(a,b)
let lcm = 0;

const multiple = (a,b,lcm)=>{
//console.log(lcm)
let i=a;
while(i<=b){
if(i==1){lcm += b; i++;};
//console.log(i,lcm)
if(i > 1 && lcm%i != 0){
lcm += b;
i++;
//console.log(i,lcm)
}else{
break
}
}
//console.log(lcm)
let arr2 = []
for(let j=a; j<b+1; j++){
arr2.push(j)
}
//console.log(arr2)
const isMultiple = (i) => lcm % i == 0;
//console.log(lcm)
if((arr2.every(isMultiple)) == false){
multiple(a,b,lcm)
}else{
console.log(lcm)
return lcm
}

}

//multiple(a,b,lcm)
console.log(multiple(a,b,lcm))
//return arr;
}

smallestCommons([1,5]);
