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 105,673,883, 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 | 105,673,883 | |
| -1 | -105,673,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,673,883.
Example:
1 x 105,673,883 = 105,673,883
and
-1 x -105,673,883 = 105,673,883
Notice both answers equal 105,673,883
With that explanation out of the way, let's continue. Next, we take the number 105,673,883 and divide it by 2:
105,673,883 ÷ 2 = 52,836,941.5
If the quotient is a whole number, then 2 and 52,836,941.5 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 | 105,673,883 | |
| -1 | -105,673,883 |
Now, we try dividing 105,673,883 by 3:
105,673,883 ÷ 3 = 35,224,627.6667
If the quotient is a whole number, then 3 and 35,224,627.6667 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 | 105,673,883 | |
| -1 | -105,673,883 |
Let's try dividing by 4:
105,673,883 ÷ 4 = 26,418,470.75
If the quotient is a whole number, then 4 and 26,418,470.75 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 | 105,673,883 | |
| -1 | 105,673,883 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 89 | 203 | 623 | 2,581 | 5,849 | 18,067 | 40,943 | 169,621 | 520,561 | 1,187,347 | 3,643,927 | 15,096,269 | 105,673,883 |
| -1 | -7 | -29 | -89 | -203 | -623 | -2,581 | -5,849 | -18,067 | -40,943 | -169,621 | -520,561 | -1,187,347 | -3,643,927 | -15,096,269 | -105,673,883 |
