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 425,640,505, 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 | 425,640,505 | |
| -1 | -425,640,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,640,505.
Example:
1 x 425,640,505 = 425,640,505
and
-1 x -425,640,505 = 425,640,505
Notice both answers equal 425,640,505
With that explanation out of the way, let's continue. Next, we take the number 425,640,505 and divide it by 2:
425,640,505 ÷ 2 = 212,820,252.5
If the quotient is a whole number, then 2 and 212,820,252.5 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 | 425,640,505 | |
| -1 | -425,640,505 |
Now, we try dividing 425,640,505 by 3:
425,640,505 ÷ 3 = 141,880,168.3333
If the quotient is a whole number, then 3 and 141,880,168.3333 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 | 425,640,505 | |
| -1 | -425,640,505 |
Let's try dividing by 4:
425,640,505 ÷ 4 = 106,410,126.25
If the quotient is a whole number, then 4 and 106,410,126.25 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 | 425,640,505 | |
| -1 | 425,640,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 137 | 181 | 685 | 905 | 3,433 | 17,165 | 24,797 | 123,985 | 470,321 | 621,373 | 2,351,605 | 3,106,865 | 85,128,101 | 425,640,505 |
| -1 | -5 | -137 | -181 | -685 | -905 | -3,433 | -17,165 | -24,797 | -123,985 | -470,321 | -621,373 | -2,351,605 | -3,106,865 | -85,128,101 | -425,640,505 |
