Javascript 求质数因数
作者:互联网
功能:输入一个正整数,按照从小到大的顺序输出它的所有质因子(重复的也要列举)(如180的质因子为2 2 3 3 5 )
const readline = require('readline');
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.on('line', function (line) {
let num = parseInt(line);
function getCode(num){
const sqrt = Math.sqrt(num);
const arr = [];
for (let i = 2; i <= sqrt; i++){
while(num % i == 0){
arr.push(i);
num /= i;
}
}
if(num != 1){
arr.push(num);
}
return arr.join(" ");
}
let res = getCode(num);
console.log(res)
});
