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 425,603,765, 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 | 425,603,765 | |
| -1 | -425,603,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,603,765.
Example:
1 x 425,603,765 = 425,603,765
and
-1 x -425,603,765 = 425,603,765
Notice both answers equal 425,603,765
With that explanation out of the way, let's continue. Next, we take the number 425,603,765 and divide it by 2:
425,603,765 ÷ 2 = 212,801,882.5
If the quotient is a whole number, then 2 and 212,801,882.5 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 | 425,603,765 | |
| -1 | -425,603,765 |
Now, we try dividing 425,603,765 by 3:
425,603,765 ÷ 3 = 141,867,921.6667
If the quotient is a whole number, then 3 and 141,867,921.6667 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 | 425,603,765 | |
| -1 | -425,603,765 |
Let's try dividing by 4:
425,603,765 ÷ 4 = 106,400,941.25
If the quotient is a whole number, then 4 and 106,400,941.25 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 | 425,603,765 | |
| -1 | 425,603,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 113 | 335 | 565 | 7,571 | 11,243 | 37,855 | 56,215 | 753,281 | 1,270,459 | 3,766,405 | 6,352,295 | 85,120,753 | 425,603,765 |
| -1 | -5 | -67 | -113 | -335 | -565 | -7,571 | -11,243 | -37,855 | -56,215 | -753,281 | -1,270,459 | -3,766,405 | -6,352,295 | -85,120,753 | -425,603,765 |
