求最大公约数，然后乘一下

const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void async function () {
    // Write your code here
    while(line = await readline()){
        let input = line.split(' ')
        let a = parseInt(input[0]);
        let b = parseInt(input[1]);

        let g = gcd(a, b);

        console.log(a * b / g);
    }
}()

function gcd(a, b){
    if(a%b === 0) return b;
    return gcd(b, a%b);
}
