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 172,352,069, 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 | 172,352,069 | |
| -1 | -172,352,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,352,069.
Example:
1 x 172,352,069 = 172,352,069
and
-1 x -172,352,069 = 172,352,069
Notice both answers equal 172,352,069
With that explanation out of the way, let's continue. Next, we take the number 172,352,069 and divide it by 2:
172,352,069 ÷ 2 = 86,176,034.5
If the quotient is a whole number, then 2 and 86,176,034.5 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 | 172,352,069 | |
| -1 | -172,352,069 |
Now, we try dividing 172,352,069 by 3:
172,352,069 ÷ 3 = 57,450,689.6667
If the quotient is a whole number, then 3 and 57,450,689.6667 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 | 172,352,069 | |
| -1 | -172,352,069 |
Let's try dividing by 4:
172,352,069 ÷ 4 = 43,088,017.25
If the quotient is a whole number, then 4 and 43,088,017.25 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 | 172,352,069 | |
| -1 | 172,352,069 |
If you did it right, you will end up with this table:
| 1 | 17 | 41 | 107 | 697 | 1,819 | 2,311 | 4,387 | 39,287 | 74,579 | 94,751 | 247,277 | 1,610,767 | 4,203,709 | 10,138,357 | 172,352,069 |
| -1 | -17 | -41 | -107 | -697 | -1,819 | -2,311 | -4,387 | -39,287 | -74,579 | -94,751 | -247,277 | -1,610,767 | -4,203,709 | -10,138,357 | -172,352,069 |
