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 172,506,529, 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 | 172,506,529 | |
| -1 | -172,506,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,506,529.
Example:
1 x 172,506,529 = 172,506,529
and
-1 x -172,506,529 = 172,506,529
Notice both answers equal 172,506,529
With that explanation out of the way, let's continue. Next, we take the number 172,506,529 and divide it by 2:
172,506,529 ÷ 2 = 86,253,264.5
If the quotient is a whole number, then 2 and 86,253,264.5 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 | 172,506,529 | |
| -1 | -172,506,529 |
Now, we try dividing 172,506,529 by 3:
172,506,529 ÷ 3 = 57,502,176.3333
If the quotient is a whole number, then 3 and 57,502,176.3333 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 | 172,506,529 | |
| -1 | -172,506,529 |
Let's try dividing by 4:
172,506,529 ÷ 4 = 43,126,632.25
If the quotient is a whole number, then 4 and 43,126,632.25 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 | 172,506,529 | |
| -1 | 172,506,529 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 29 | 247 | 377 | 551 | 7,163 | 24,083 | 313,079 | 457,577 | 698,407 | 5,948,501 | 9,079,291 | 13,269,733 | 172,506,529 |
| -1 | -13 | -19 | -29 | -247 | -377 | -551 | -7,163 | -24,083 | -313,079 | -457,577 | -698,407 | -5,948,501 | -9,079,291 | -13,269,733 | -172,506,529 |
