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 173,412,733, 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 | 173,412,733 | |
| -1 | -173,412,733 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,412,733.
Example:
1 x 173,412,733 = 173,412,733
and
-1 x -173,412,733 = 173,412,733
Notice both answers equal 173,412,733
With that explanation out of the way, let's continue. Next, we take the number 173,412,733 and divide it by 2:
173,412,733 ÷ 2 = 86,706,366.5
If the quotient is a whole number, then 2 and 86,706,366.5 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 | 173,412,733 | |
| -1 | -173,412,733 |
Now, we try dividing 173,412,733 by 3:
173,412,733 ÷ 3 = 57,804,244.3333
If the quotient is a whole number, then 3 and 57,804,244.3333 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 | 173,412,733 | |
| -1 | -173,412,733 |
Let's try dividing by 4:
173,412,733 ÷ 4 = 43,353,183.25
If the quotient is a whole number, then 4 and 43,353,183.25 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 | 173,412,733 | |
| -1 | 173,412,733 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 269 | 2,917 | 3,497 | 4,573 | 37,921 | 49,589 | 59,449 | 644,657 | 784,673 | 10,200,749 | 13,339,441 | 173,412,733 |
| -1 | -13 | -17 | -221 | -269 | -2,917 | -3,497 | -4,573 | -37,921 | -49,589 | -59,449 | -644,657 | -784,673 | -10,200,749 | -13,339,441 | -173,412,733 |
