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 173,725,465, 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 | 173,725,465 | |
| -1 | -173,725,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,725,465.
Example:
1 x 173,725,465 = 173,725,465
and
-1 x -173,725,465 = 173,725,465
Notice both answers equal 173,725,465
With that explanation out of the way, let's continue. Next, we take the number 173,725,465 and divide it by 2:
173,725,465 ÷ 2 = 86,862,732.5
If the quotient is a whole number, then 2 and 86,862,732.5 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 | 173,725,465 | |
| -1 | -173,725,465 |
Now, we try dividing 173,725,465 by 3:
173,725,465 ÷ 3 = 57,908,488.3333
If the quotient is a whole number, then 3 and 57,908,488.3333 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 | 173,725,465 | |
| -1 | -173,725,465 |
Let's try dividing by 4:
173,725,465 ÷ 4 = 43,431,366.25
If the quotient is a whole number, then 4 and 43,431,366.25 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 | 173,725,465 | |
| -1 | 173,725,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 103 | 515 | 1,751 | 8,755 | 19,843 | 99,215 | 337,331 | 1,686,655 | 2,043,829 | 10,219,145 | 34,745,093 | 173,725,465 |
| -1 | -5 | -17 | -85 | -103 | -515 | -1,751 | -8,755 | -19,843 | -99,215 | -337,331 | -1,686,655 | -2,043,829 | -10,219,145 | -34,745,093 | -173,725,465 |
