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 116,685,905, 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 | 116,685,905 | |
| -1 | -116,685,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,685,905.
Example:
1 x 116,685,905 = 116,685,905
and
-1 x -116,685,905 = 116,685,905
Notice both answers equal 116,685,905
With that explanation out of the way, let's continue. Next, we take the number 116,685,905 and divide it by 2:
116,685,905 ÷ 2 = 58,342,952.5
If the quotient is a whole number, then 2 and 58,342,952.5 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 | 116,685,905 | |
| -1 | -116,685,905 |
Now, we try dividing 116,685,905 by 3:
116,685,905 ÷ 3 = 38,895,301.6667
If the quotient is a whole number, then 3 and 38,895,301.6667 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 | 116,685,905 | |
| -1 | -116,685,905 |
Let's try dividing by 4:
116,685,905 ÷ 4 = 29,171,476.25
If the quotient is a whole number, then 4 and 29,171,476.25 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 | 116,685,905 | |
| -1 | 116,685,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 173 | 245 | 865 | 1,211 | 2,753 | 6,055 | 8,477 | 13,765 | 19,271 | 42,385 | 96,355 | 134,897 | 476,269 | 674,485 | 2,381,345 | 3,333,883 | 16,669,415 | 23,337,181 | 116,685,905 |
| -1 | -5 | -7 | -35 | -49 | -173 | -245 | -865 | -1,211 | -2,753 | -6,055 | -8,477 | -13,765 | -19,271 | -42,385 | -96,355 | -134,897 | -476,269 | -674,485 | -2,381,345 | -3,333,883 | -16,669,415 | -23,337,181 | -116,685,905 |
