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 425,064,125, 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 | 425,064,125 | |
| -1 | -425,064,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 425,064,125.
Example:
1 x 425,064,125 = 425,064,125
and
-1 x -425,064,125 = 425,064,125
Notice both answers equal 425,064,125
With that explanation out of the way, let's continue. Next, we take the number 425,064,125 and divide it by 2:
425,064,125 ÷ 2 = 212,532,062.5
If the quotient is a whole number, then 2 and 212,532,062.5 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 | 425,064,125 | |
| -1 | -425,064,125 |
Now, we try dividing 425,064,125 by 3:
425,064,125 ÷ 3 = 141,688,041.6667
If the quotient is a whole number, then 3 and 141,688,041.6667 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 | 425,064,125 | |
| -1 | -425,064,125 |
Let's try dividing by 4:
425,064,125 ÷ 4 = 106,266,031.25
If the quotient is a whole number, then 4 and 106,266,031.25 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 | 425,064,125 | |
| -1 | 425,064,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 1,237 | 2,749 | 6,185 | 13,745 | 30,925 | 68,725 | 154,625 | 343,625 | 3,400,513 | 17,002,565 | 85,012,825 | 425,064,125 |
| -1 | -5 | -25 | -125 | -1,237 | -2,749 | -6,185 | -13,745 | -30,925 | -68,725 | -154,625 | -343,625 | -3,400,513 | -17,002,565 | -85,012,825 | -425,064,125 |
