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 172,732,553, 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 | 172,732,553 | |
| -1 | -172,732,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,732,553.
Example:
1 x 172,732,553 = 172,732,553
and
-1 x -172,732,553 = 172,732,553
Notice both answers equal 172,732,553
With that explanation out of the way, let's continue. Next, we take the number 172,732,553 and divide it by 2:
172,732,553 ÷ 2 = 86,366,276.5
If the quotient is a whole number, then 2 and 86,366,276.5 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 | 172,732,553 | |
| -1 | -172,732,553 |
Now, we try dividing 172,732,553 by 3:
172,732,553 ÷ 3 = 57,577,517.6667
If the quotient is a whole number, then 3 and 57,577,517.6667 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 | 172,732,553 | |
| -1 | -172,732,553 |
Let's try dividing by 4:
172,732,553 ÷ 4 = 43,183,138.25
If the quotient is a whole number, then 4 and 43,183,138.25 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 | 172,732,553 | |
| -1 | 172,732,553 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 133 | 161 | 437 | 3,059 | 56,467 | 395,269 | 1,072,873 | 1,298,741 | 7,510,111 | 9,091,187 | 24,676,079 | 172,732,553 |
| -1 | -7 | -19 | -23 | -133 | -161 | -437 | -3,059 | -56,467 | -395,269 | -1,072,873 | -1,298,741 | -7,510,111 | -9,091,187 | -24,676,079 | -172,732,553 |
