2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.
What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?
int times = 0;
for (int i=1; i<1000000000; i++) {
for (int j=1; j<=20; j++) {
if (i%j==0) {
times++;
}
}
if (times==20) {
System.out.println(i);
break;
}
times = 0;
}
