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 425,134,745, 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 | 425,134,745 | |
| -1 | -425,134,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,134,745.
Example:
1 x 425,134,745 = 425,134,745
and
-1 x -425,134,745 = 425,134,745
Notice both answers equal 425,134,745
With that explanation out of the way, let's continue. Next, we take the number 425,134,745 and divide it by 2:
425,134,745 ÷ 2 = 212,567,372.5
If the quotient is a whole number, then 2 and 212,567,372.5 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 | 425,134,745 | |
| -1 | -425,134,745 |
Now, we try dividing 425,134,745 by 3:
425,134,745 ÷ 3 = 141,711,581.6667
If the quotient is a whole number, then 3 and 141,711,581.6667 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 | 425,134,745 | |
| -1 | -425,134,745 |
Let's try dividing by 4:
425,134,745 ÷ 4 = 106,283,686.25
If the quotient is a whole number, then 4 and 106,283,686.25 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 | 425,134,745 | |
| -1 | 425,134,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 331 | 1,655 | 2,317 | 11,585 | 36,697 | 183,485 | 256,879 | 1,284,395 | 12,146,707 | 60,733,535 | 85,026,949 | 425,134,745 |
| -1 | -5 | -7 | -35 | -331 | -1,655 | -2,317 | -11,585 | -36,697 | -183,485 | -256,879 | -1,284,395 | -12,146,707 | -60,733,535 | -85,026,949 | -425,134,745 |
