For Loop Multiplying Number

I need some help -

At the end of a for loop, I need to set an original value to the next multiple of the value.

This is what I have so far -

int originalNumber = 1;
for (int i = 1; i <= 10000; i++) { 
  originalNumber *= i;
 }

However, this code will not find the multiples of 1; as the multiples of 1 should be (1, 2, 3, 4, 5, 6, ... ...)

This code that I have written will be (1, 1, 2, 6, 24) etc;

What is a good way to get the multiples (inside of the loop)?

 int n = scanner.nextInt();
       for (int i = 1; i <= 10;  i++){
         int multiple = i * n;
         System.out.println(n + " x " + i + " = " + multiple);
        }

You can try this code, it prints any multiple till 10; Your Output (stdout) 2 x 1 = 2
2 x 2 = 4 ... 2 x 10 = 20

You ask for version without additional variable:

int originalNumber = 1;
for (int multiple = originalNumber; multiple <= 10000; multiple += originalNumber) {
    // Use multiple however you want to
}

You don't need to change originalNumber at all - just multiply i by originalNumber:

int originalNumber = 1;
for (int i = 1; i <= 10000; i++) {
    int multiple = originalNumber * i;
    // Use multiple however you want to
}

To get all the multiples of 2, you'd set originalNumber to 2, etc.
