Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 21,600,359, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 21,600,359 | |
| -1 | -21,600,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,600,359.
Example:
1 x 21,600,359 = 21,600,359
and
-1 x -21,600,359 = 21,600,359
Notice both answers equal 21,600,359
With that explanation out of the way, let's continue. Next, we take the number 21,600,359 and divide it by 2:
21,600,359 ÷ 2 = 10,800,179.5
If the quotient is a whole number, then 2 and 10,800,179.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 21,600,359 | |
| -1 | -21,600,359 |
Now, we try dividing 21,600,359 by 3:
21,600,359 ÷ 3 = 7,200,119.6667
If the quotient is a whole number, then 3 and 7,200,119.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 21,600,359 | |
| -1 | -21,600,359 |
Let's try dividing by 4:
21,600,359 ÷ 4 = 5,400,089.75
If the quotient is a whole number, then 4 and 5,400,089.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 21,600,359 | |
| -1 | 21,600,359 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 181 | 209 | 571 | 1,991 | 3,439 | 6,281 | 10,849 | 37,829 | 103,351 | 119,339 | 1,136,861 | 1,963,669 | 21,600,359 |
| -1 | -11 | -19 | -181 | -209 | -571 | -1,991 | -3,439 | -6,281 | -10,849 | -37,829 | -103,351 | -119,339 | -1,136,861 | -1,963,669 | -21,600,359 |
