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 425,032,111, 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 | 425,032,111 | |
| -1 | -425,032,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,032,111.
Example:
1 x 425,032,111 = 425,032,111
and
-1 x -425,032,111 = 425,032,111
Notice both answers equal 425,032,111
With that explanation out of the way, let's continue. Next, we take the number 425,032,111 and divide it by 2:
425,032,111 ÷ 2 = 212,516,055.5
If the quotient is a whole number, then 2 and 212,516,055.5 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 | 425,032,111 | |
| -1 | -425,032,111 |
Now, we try dividing 425,032,111 by 3:
425,032,111 ÷ 3 = 141,677,370.3333
If the quotient is a whole number, then 3 and 141,677,370.3333 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 | 425,032,111 | |
| -1 | -425,032,111 |
Let's try dividing by 4:
425,032,111 ÷ 4 = 106,258,027.75
If the quotient is a whole number, then 4 and 106,258,027.75 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 | 425,032,111 | |
| -1 | 425,032,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 467 | 3,269 | 5,653 | 10,741 | 39,571 | 75,187 | 130,019 | 910,133 | 2,639,951 | 18,479,657 | 60,718,873 | 425,032,111 |
| -1 | -7 | -23 | -161 | -467 | -3,269 | -5,653 | -10,741 | -39,571 | -75,187 | -130,019 | -910,133 | -2,639,951 | -18,479,657 | -60,718,873 | -425,032,111 |
