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 172,751,117, 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 | 172,751,117 | |
| -1 | -172,751,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,751,117.
Example:
1 x 172,751,117 = 172,751,117
and
-1 x -172,751,117 = 172,751,117
Notice both answers equal 172,751,117
With that explanation out of the way, let's continue. Next, we take the number 172,751,117 and divide it by 2:
172,751,117 ÷ 2 = 86,375,558.5
If the quotient is a whole number, then 2 and 86,375,558.5 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 | 172,751,117 | |
| -1 | -172,751,117 |
Now, we try dividing 172,751,117 by 3:
172,751,117 ÷ 3 = 57,583,705.6667
If the quotient is a whole number, then 3 and 57,583,705.6667 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 | 172,751,117 | |
| -1 | -172,751,117 |
Let's try dividing by 4:
172,751,117 ÷ 4 = 43,187,779.25
If the quotient is a whole number, then 4 and 43,187,779.25 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 | 172,751,117 | |
| -1 | 172,751,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 79 | 539 | 553 | 869 | 3,871 | 4,057 | 6,083 | 28,399 | 42,581 | 44,627 | 198,793 | 312,389 | 320,503 | 2,186,723 | 2,243,521 | 3,525,533 | 15,704,647 | 24,678,731 | 172,751,117 |
| -1 | -7 | -11 | -49 | -77 | -79 | -539 | -553 | -869 | -3,871 | -4,057 | -6,083 | -28,399 | -42,581 | -44,627 | -198,793 | -312,389 | -320,503 | -2,186,723 | -2,243,521 | -3,525,533 | -15,704,647 | -24,678,731 | -172,751,117 |
