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 207,430,559, 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 | 207,430,559 | |
| -1 | -207,430,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 207,430,559.
Example:
1 x 207,430,559 = 207,430,559
and
-1 x -207,430,559 = 207,430,559
Notice both answers equal 207,430,559
With that explanation out of the way, let's continue. Next, we take the number 207,430,559 and divide it by 2:
207,430,559 ÷ 2 = 103,715,279.5
If the quotient is a whole number, then 2 and 103,715,279.5 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 | 207,430,559 | |
| -1 | -207,430,559 |
Now, we try dividing 207,430,559 by 3:
207,430,559 ÷ 3 = 69,143,519.6667
If the quotient is a whole number, then 3 and 69,143,519.6667 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 | 207,430,559 | |
| -1 | -207,430,559 |
Let's try dividing by 4:
207,430,559 ÷ 4 = 51,857,639.75
If the quotient is a whole number, then 4 and 51,857,639.75 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 | 207,430,559 | |
| -1 | 207,430,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 197 | 359 | 419 | 1,379 | 2,513 | 2,933 | 70,723 | 82,543 | 150,421 | 495,061 | 577,801 | 1,052,947 | 29,632,937 | 207,430,559 |
| -1 | -7 | -197 | -359 | -419 | -1,379 | -2,513 | -2,933 | -70,723 | -82,543 | -150,421 | -495,061 | -577,801 | -1,052,947 | -29,632,937 | -207,430,559 |
