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 173,417,465, 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 | 173,417,465 | |
| -1 | -173,417,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,417,465.
Example:
1 x 173,417,465 = 173,417,465
and
-1 x -173,417,465 = 173,417,465
Notice both answers equal 173,417,465
With that explanation out of the way, let's continue. Next, we take the number 173,417,465 and divide it by 2:
173,417,465 ÷ 2 = 86,708,732.5
If the quotient is a whole number, then 2 and 86,708,732.5 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 | 173,417,465 | |
| -1 | -173,417,465 |
Now, we try dividing 173,417,465 by 3:
173,417,465 ÷ 3 = 57,805,821.6667
If the quotient is a whole number, then 3 and 57,805,821.6667 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 | 173,417,465 | |
| -1 | -173,417,465 |
Let's try dividing by 4:
173,417,465 ÷ 4 = 43,354,366.25
If the quotient is a whole number, then 4 and 43,354,366.25 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 | 173,417,465 | |
| -1 | 173,417,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 140,419 | 702,095 | 1,825,447 | 2,667,961 | 9,127,235 | 13,339,805 | 34,683,493 | 173,417,465 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -140,419 | -702,095 | -1,825,447 | -2,667,961 | -9,127,235 | -13,339,805 | -34,683,493 | -173,417,465 |
