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 172,732,555, 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 | 172,732,555 | |
| -1 | -172,732,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 172,732,555.
Example:
1 x 172,732,555 = 172,732,555
and
-1 x -172,732,555 = 172,732,555
Notice both answers equal 172,732,555
With that explanation out of the way, let's continue. Next, we take the number 172,732,555 and divide it by 2:
172,732,555 ÷ 2 = 86,366,277.5
If the quotient is a whole number, then 2 and 86,366,277.5 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 | 172,732,555 | |
| -1 | -172,732,555 |
Now, we try dividing 172,732,555 by 3:
172,732,555 ÷ 3 = 57,577,518.3333
If the quotient is a whole number, then 3 and 57,577,518.3333 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 | 172,732,555 | |
| -1 | -172,732,555 |
Let's try dividing by 4:
172,732,555 ÷ 4 = 43,183,138.75
If the quotient is a whole number, then 4 and 43,183,138.75 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 | 172,732,555 | |
| -1 | 172,732,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 197 | 985 | 5,713 | 6,047 | 28,565 | 30,235 | 175,363 | 876,815 | 1,191,259 | 5,956,295 | 34,546,511 | 172,732,555 |
| -1 | -5 | -29 | -145 | -197 | -985 | -5,713 | -6,047 | -28,565 | -30,235 | -175,363 | -876,815 | -1,191,259 | -5,956,295 | -34,546,511 | -172,732,555 |
