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 118,744,355, 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 | 118,744,355 | |
| -1 | -118,744,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,744,355.
Example:
1 x 118,744,355 = 118,744,355
and
-1 x -118,744,355 = 118,744,355
Notice both answers equal 118,744,355
With that explanation out of the way, let's continue. Next, we take the number 118,744,355 and divide it by 2:
118,744,355 ÷ 2 = 59,372,177.5
If the quotient is a whole number, then 2 and 59,372,177.5 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 | 118,744,355 | |
| -1 | -118,744,355 |
Now, we try dividing 118,744,355 by 3:
118,744,355 ÷ 3 = 39,581,451.6667
If the quotient is a whole number, then 3 and 39,581,451.6667 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 | 118,744,355 | |
| -1 | -118,744,355 |
Let's try dividing by 4:
118,744,355 ÷ 4 = 29,686,088.75
If the quotient is a whole number, then 4 and 29,686,088.75 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 | 118,744,355 | |
| -1 | 118,744,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 113 | 365 | 565 | 2,879 | 8,249 | 14,395 | 41,245 | 210,167 | 325,327 | 1,050,835 | 1,626,635 | 23,748,871 | 118,744,355 |
| -1 | -5 | -73 | -113 | -365 | -565 | -2,879 | -8,249 | -14,395 | -41,245 | -210,167 | -325,327 | -1,050,835 | -1,626,635 | -23,748,871 | -118,744,355 |
