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 118,741,753, 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 | 118,741,753 | |
| -1 | -118,741,753 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,741,753.
Example:
1 x 118,741,753 = 118,741,753
and
-1 x -118,741,753 = 118,741,753
Notice both answers equal 118,741,753
With that explanation out of the way, let's continue. Next, we take the number 118,741,753 and divide it by 2:
118,741,753 ÷ 2 = 59,370,876.5
If the quotient is a whole number, then 2 and 59,370,876.5 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 | 118,741,753 | |
| -1 | -118,741,753 |
Now, we try dividing 118,741,753 by 3:
118,741,753 ÷ 3 = 39,580,584.3333
If the quotient is a whole number, then 3 and 39,580,584.3333 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 | 118,741,753 | |
| -1 | -118,741,753 |
Let's try dividing by 4:
118,741,753 ÷ 4 = 29,685,438.25
If the quotient is a whole number, then 4 and 29,685,438.25 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 | 118,741,753 | |
| -1 | 118,741,753 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 89 | 221 | 1,157 | 1,513 | 6,037 | 19,669 | 78,481 | 102,629 | 537,293 | 1,334,177 | 6,984,809 | 9,133,981 | 118,741,753 |
| -1 | -13 | -17 | -89 | -221 | -1,157 | -1,513 | -6,037 | -19,669 | -78,481 | -102,629 | -537,293 | -1,334,177 | -6,984,809 | -9,133,981 | -118,741,753 |
