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 118,543,313, 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 | 118,543,313 | |
| -1 | -118,543,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,543,313.
Example:
1 x 118,543,313 = 118,543,313
and
-1 x -118,543,313 = 118,543,313
Notice both answers equal 118,543,313
With that explanation out of the way, let's continue. Next, we take the number 118,543,313 and divide it by 2:
118,543,313 ÷ 2 = 59,271,656.5
If the quotient is a whole number, then 2 and 59,271,656.5 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 | 118,543,313 | |
| -1 | -118,543,313 |
Now, we try dividing 118,543,313 by 3:
118,543,313 ÷ 3 = 39,514,437.6667
If the quotient is a whole number, then 3 and 39,514,437.6667 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 | 118,543,313 | |
| -1 | -118,543,313 |
Let's try dividing by 4:
118,543,313 ÷ 4 = 29,635,828.25
If the quotient is a whole number, then 4 and 29,635,828.25 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 | 118,543,313 | |
| -1 | 118,543,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 73 | 427 | 511 | 3,803 | 4,453 | 26,621 | 31,171 | 231,983 | 277,619 | 1,623,881 | 1,943,333 | 16,934,759 | 118,543,313 |
| -1 | -7 | -61 | -73 | -427 | -511 | -3,803 | -4,453 | -26,621 | -31,171 | -231,983 | -277,619 | -1,623,881 | -1,943,333 | -16,934,759 | -118,543,313 |
