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 173,841,689, 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 | 173,841,689 | |
| -1 | -173,841,689 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,841,689.
Example:
1 x 173,841,689 = 173,841,689
and
-1 x -173,841,689 = 173,841,689
Notice both answers equal 173,841,689
With that explanation out of the way, let's continue. Next, we take the number 173,841,689 and divide it by 2:
173,841,689 ÷ 2 = 86,920,844.5
If the quotient is a whole number, then 2 and 86,920,844.5 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 | 173,841,689 | |
| -1 | -173,841,689 |
Now, we try dividing 173,841,689 by 3:
173,841,689 ÷ 3 = 57,947,229.6667
If the quotient is a whole number, then 3 and 57,947,229.6667 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 | 173,841,689 | |
| -1 | -173,841,689 |
Let's try dividing by 4:
173,841,689 ÷ 4 = 43,460,422.25
If the quotient is a whole number, then 4 and 43,460,422.25 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 | 173,841,689 | |
| -1 | 173,841,689 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 73 | 203 | 511 | 2,117 | 11,731 | 14,819 | 82,117 | 340,199 | 856,363 | 2,381,393 | 5,994,541 | 24,834,527 | 173,841,689 |
| -1 | -7 | -29 | -73 | -203 | -511 | -2,117 | -11,731 | -14,819 | -82,117 | -340,199 | -856,363 | -2,381,393 | -5,994,541 | -24,834,527 | -173,841,689 |
