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 118,775,545, 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 | 118,775,545 | |
| -1 | -118,775,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,775,545.
Example:
1 x 118,775,545 = 118,775,545
and
-1 x -118,775,545 = 118,775,545
Notice both answers equal 118,775,545
With that explanation out of the way, let's continue. Next, we take the number 118,775,545 and divide it by 2:
118,775,545 ÷ 2 = 59,387,772.5
If the quotient is a whole number, then 2 and 59,387,772.5 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 | 118,775,545 | |
| -1 | -118,775,545 |
Now, we try dividing 118,775,545 by 3:
118,775,545 ÷ 3 = 39,591,848.3333
If the quotient is a whole number, then 3 and 39,591,848.3333 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 | 118,775,545 | |
| -1 | -118,775,545 |
Let's try dividing by 4:
118,775,545 ÷ 4 = 29,693,886.25
If the quotient is a whole number, then 4 and 29,693,886.25 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 | 118,775,545 | |
| -1 | 118,775,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 47,797 | 238,985 | 334,579 | 1,672,895 | 3,393,587 | 16,967,935 | 23,755,109 | 118,775,545 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -47,797 | -238,985 | -334,579 | -1,672,895 | -3,393,587 | -16,967,935 | -23,755,109 | -118,775,545 |
