These are the two functions you need:

public static int lcm(int i1, int i2) {

return (i1*i2/gcd(i1,i2));

}

public static int gcd(int i1, int i2) {

// using Euclid's algorithm

int a=i1, b=i2, temp;

while (b!=0) {

temp=b;

b=a%temp;

a=temp;

}

return a;

}

where to start? do you have an algorithm and just want to implement it in java? depends on how big N is, as that will determine which method is most efficient

Add the numbers into one variable as you read them in. But if you prefer, you can read the numbers into an array and then use a loop to add the numbers together.

This is a very simple problem, alnost certainly a homework problem, and you should make an effort to answer it yourself.

I found this class that defines complex numbers, and has the capacity of adding them, and much more: http://www.math.ksu.edu/~bennett/jomacg/c.html Basically, you define a class with two fields, one for the real part, and one for the imaginary part.
