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 553,025,435, 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 | 553,025,435 | |
| -1 | -553,025,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 553,025,435.
Example:
1 x 553,025,435 = 553,025,435
and
-1 x -553,025,435 = 553,025,435
Notice both answers equal 553,025,435
With that explanation out of the way, let's continue. Next, we take the number 553,025,435 and divide it by 2:
553,025,435 ÷ 2 = 276,512,717.5
If the quotient is a whole number, then 2 and 276,512,717.5 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 | 553,025,435 | |
| -1 | -553,025,435 |
Now, we try dividing 553,025,435 by 3:
553,025,435 ÷ 3 = 184,341,811.6667
If the quotient is a whole number, then 3 and 184,341,811.6667 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 | 553,025,435 | |
| -1 | -553,025,435 |
Let's try dividing by 4:
553,025,435 ÷ 4 = 138,256,358.75
If the quotient is a whole number, then 4 and 138,256,358.75 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 | 553,025,435 | |
| -1 | 553,025,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 157 | 433 | 785 | 1,627 | 2,165 | 8,135 | 67,981 | 255,439 | 339,905 | 704,491 | 1,277,195 | 3,522,455 | 110,605,087 | 553,025,435 |
| -1 | -5 | -157 | -433 | -785 | -1,627 | -2,165 | -8,135 | -67,981 | -255,439 | -339,905 | -704,491 | -1,277,195 | -3,522,455 | -110,605,087 | -553,025,435 |
