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 173,387,483, 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 | 173,387,483 | |
| -1 | -173,387,483 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,387,483.
Example:
1 x 173,387,483 = 173,387,483
and
-1 x -173,387,483 = 173,387,483
Notice both answers equal 173,387,483
With that explanation out of the way, let's continue. Next, we take the number 173,387,483 and divide it by 2:
173,387,483 ÷ 2 = 86,693,741.5
If the quotient is a whole number, then 2 and 86,693,741.5 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 | 173,387,483 | |
| -1 | -173,387,483 |
Now, we try dividing 173,387,483 by 3:
173,387,483 ÷ 3 = 57,795,827.6667
If the quotient is a whole number, then 3 and 57,795,827.6667 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 | 173,387,483 | |
| -1 | -173,387,483 |
Let's try dividing by 4:
173,387,483 ÷ 4 = 43,346,870.75
If the quotient is a whole number, then 4 and 43,346,870.75 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 | 173,387,483 | |
| -1 | 173,387,483 |
If you did it right, you will end up with this table:
| 1 | 19 | 41 | 73 | 779 | 1,387 | 2,993 | 3,049 | 56,867 | 57,931 | 125,009 | 222,577 | 2,375,171 | 4,228,963 | 9,125,657 | 173,387,483 |
| -1 | -19 | -41 | -73 | -779 | -1,387 | -2,993 | -3,049 | -56,867 | -57,931 | -125,009 | -222,577 | -2,375,171 | -4,228,963 | -9,125,657 | -173,387,483 |
