Thread: I don't understand this. Please help...

the year is 2013. the CEO appointed new managers of accounts,finance,sales. the term for the accounts manager is 4 years, the term for the finance manager is 5 years and the term for the sales manager is 8 years. Write a java program to determin and print the next year in which new managers will be appointed for all three departments.

this is my code so far:

import java.util.*;
public class Program1{
	public static void main (String [] args){
		Scanner in = new Scanner (System.in);
int year=2013,acc=2013,fin=2013,sales=2013;
for(year=2013;year <= 2017;year ++) acc ++;
for(year=2013;year <= 2018;year ++) fin ++;
for(year=2013;year <= 2021;year ++) sales ++;
 
System.out.printf("The new Accounts manager will be appointed in the year: %d\n",acc);
System.out.printf("The new Finance manager will be appointed in the year: %d\n",fin);
System.out.printf("The new Sales manager will be appointed in the year: %d\n",sales);
	}
}

The program prints out the correct year for when someone new is supposed to be appointed for all of the offices. What is the problem?

Yeah it prints the correct year for each of the different managers.But i think i interpreted the question wrong because it says "print the next year in which new managers will be appointed for all three departments" With emphasis on the word year. So i dont understand how to code that.

It's a least common multiple (LCM) problem. All 3 managers were appointed in 2013 and will each be replaced in 4, 5, and 8 year intervals from 2013. The problem is asking you to write a program that will compute the next year (like 2013) in which all managers will be replaced. Find the LCM of 4, 5, and 8 and add to 2013 to find the answer.
