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 118,536,925, 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 | 118,536,925 | |
| -1 | -118,536,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,536,925.
Example:
1 x 118,536,925 = 118,536,925
and
-1 x -118,536,925 = 118,536,925
Notice both answers equal 118,536,925
With that explanation out of the way, let's continue. Next, we take the number 118,536,925 and divide it by 2:
118,536,925 ÷ 2 = 59,268,462.5
If the quotient is a whole number, then 2 and 59,268,462.5 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 | 118,536,925 | |
| -1 | -118,536,925 |
Now, we try dividing 118,536,925 by 3:
118,536,925 ÷ 3 = 39,512,308.3333
If the quotient is a whole number, then 3 and 39,512,308.3333 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 | 118,536,925 | |
| -1 | -118,536,925 |
Let's try dividing by 4:
118,536,925 ÷ 4 = 29,634,231.25
If the quotient is a whole number, then 4 and 29,634,231.25 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 | 118,536,925 | |
| -1 | 118,536,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 325 | 569 | 641 | 2,845 | 3,205 | 7,397 | 8,333 | 14,225 | 16,025 | 36,985 | 41,665 | 184,925 | 208,325 | 364,729 | 1,823,645 | 4,741,477 | 9,118,225 | 23,707,385 | 118,536,925 |
| -1 | -5 | -13 | -25 | -65 | -325 | -569 | -641 | -2,845 | -3,205 | -7,397 | -8,333 | -14,225 | -16,025 | -36,985 | -41,665 | -184,925 | -208,325 | -364,729 | -1,823,645 | -4,741,477 | -9,118,225 | -23,707,385 | -118,536,925 |
