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 172,753,273, 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 | 172,753,273 | |
| -1 | -172,753,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,753,273.
Example:
1 x 172,753,273 = 172,753,273
and
-1 x -172,753,273 = 172,753,273
Notice both answers equal 172,753,273
With that explanation out of the way, let's continue. Next, we take the number 172,753,273 and divide it by 2:
172,753,273 ÷ 2 = 86,376,636.5
If the quotient is a whole number, then 2 and 86,376,636.5 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 | 172,753,273 | |
| -1 | -172,753,273 |
Now, we try dividing 172,753,273 by 3:
172,753,273 ÷ 3 = 57,584,424.3333
If the quotient is a whole number, then 3 and 57,584,424.3333 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 | 172,753,273 | |
| -1 | -172,753,273 |
Let's try dividing by 4:
172,753,273 ÷ 4 = 43,188,318.25
If the quotient is a whole number, then 4 and 43,188,318.25 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 | 172,753,273 | |
| -1 | 172,753,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 539 | 847 | 5,929 | 29,137 | 203,959 | 320,507 | 1,427,713 | 2,243,549 | 3,525,577 | 15,704,843 | 24,679,039 | 172,753,273 |
| -1 | -7 | -11 | -49 | -77 | -121 | -539 | -847 | -5,929 | -29,137 | -203,959 | -320,507 | -1,427,713 | -2,243,549 | -3,525,577 | -15,704,843 | -24,679,039 | -172,753,273 |
