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 113,668,783, 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 | 113,668,783 | |
| -1 | -113,668,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,668,783.
Example:
1 x 113,668,783 = 113,668,783
and
-1 x -113,668,783 = 113,668,783
Notice both answers equal 113,668,783
With that explanation out of the way, let's continue. Next, we take the number 113,668,783 and divide it by 2:
113,668,783 ÷ 2 = 56,834,391.5
If the quotient is a whole number, then 2 and 56,834,391.5 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 | 113,668,783 | |
| -1 | -113,668,783 |
Now, we try dividing 113,668,783 by 3:
113,668,783 ÷ 3 = 37,889,594.3333
If the quotient is a whole number, then 3 and 37,889,594.3333 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 | 113,668,783 | |
| -1 | -113,668,783 |
Let's try dividing by 4:
113,668,783 ÷ 4 = 28,417,195.75
If the quotient is a whole number, then 4 and 28,417,195.75 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 | 113,668,783 | |
| -1 | 113,668,783 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 67 | 391 | 1,139 | 1,541 | 4,339 | 26,197 | 73,763 | 99,797 | 290,713 | 1,696,549 | 4,942,121 | 6,686,399 | 113,668,783 |
| -1 | -17 | -23 | -67 | -391 | -1,139 | -1,541 | -4,339 | -26,197 | -73,763 | -99,797 | -290,713 | -1,696,549 | -4,942,121 | -6,686,399 | -113,668,783 |
