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 425,607,061, 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 | 425,607,061 | |
| -1 | -425,607,061 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,607,061.
Example:
1 x 425,607,061 = 425,607,061
and
-1 x -425,607,061 = 425,607,061
Notice both answers equal 425,607,061
With that explanation out of the way, let's continue. Next, we take the number 425,607,061 and divide it by 2:
425,607,061 ÷ 2 = 212,803,530.5
If the quotient is a whole number, then 2 and 212,803,530.5 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 | 425,607,061 | |
| -1 | -425,607,061 |
Now, we try dividing 425,607,061 by 3:
425,607,061 ÷ 3 = 141,869,020.3333
If the quotient is a whole number, then 3 and 141,869,020.3333 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 | 425,607,061 | |
| -1 | -425,607,061 |
Let's try dividing by 4:
425,607,061 ÷ 4 = 106,401,765.25
If the quotient is a whole number, then 4 and 106,401,765.25 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 | 425,607,061 | |
| -1 | 425,607,061 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 157 | 649 | 1,727 | 4,177 | 9,263 | 45,947 | 101,893 | 246,443 | 655,789 | 2,710,873 | 7,213,679 | 38,691,551 | 425,607,061 |
| -1 | -11 | -59 | -157 | -649 | -1,727 | -4,177 | -9,263 | -45,947 | -101,893 | -246,443 | -655,789 | -2,710,873 | -7,213,679 | -38,691,551 | -425,607,061 |
