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 116,018,531, 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 | 116,018,531 | |
| -1 | -116,018,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,018,531.
Example:
1 x 116,018,531 = 116,018,531
and
-1 x -116,018,531 = 116,018,531
Notice both answers equal 116,018,531
With that explanation out of the way, let's continue. Next, we take the number 116,018,531 and divide it by 2:
116,018,531 ÷ 2 = 58,009,265.5
If the quotient is a whole number, then 2 and 58,009,265.5 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 | 116,018,531 | |
| -1 | -116,018,531 |
Now, we try dividing 116,018,531 by 3:
116,018,531 ÷ 3 = 38,672,843.6667
If the quotient is a whole number, then 3 and 38,672,843.6667 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 | 116,018,531 | |
| -1 | -116,018,531 |
Let's try dividing by 4:
116,018,531 ÷ 4 = 29,004,632.75
If the quotient is a whole number, then 4 and 29,004,632.75 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 | 116,018,531 | |
| -1 | 116,018,531 |
If you did it right, you will end up with this table:
| 1 | 29 | 79 | 89 | 569 | 2,291 | 2,581 | 7,031 | 16,501 | 44,951 | 50,641 | 203,899 | 1,303,579 | 1,468,589 | 4,000,639 | 116,018,531 |
| -1 | -29 | -79 | -89 | -569 | -2,291 | -2,581 | -7,031 | -16,501 | -44,951 | -50,641 | -203,899 | -1,303,579 | -1,468,589 | -4,000,639 | -116,018,531 |
