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 119,850,355, 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 | 119,850,355 | |
| -1 | -119,850,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 119,850,355.
Example:
1 x 119,850,355 = 119,850,355
and
-1 x -119,850,355 = 119,850,355
Notice both answers equal 119,850,355
With that explanation out of the way, let's continue. Next, we take the number 119,850,355 and divide it by 2:
119,850,355 ÷ 2 = 59,925,177.5
If the quotient is a whole number, then 2 and 59,925,177.5 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 | 119,850,355 | |
| -1 | -119,850,355 |
Now, we try dividing 119,850,355 by 3:
119,850,355 ÷ 3 = 39,950,118.3333
If the quotient is a whole number, then 3 and 39,950,118.3333 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 | 119,850,355 | |
| -1 | -119,850,355 |
Let's try dividing by 4:
119,850,355 ÷ 4 = 29,962,588.75
If the quotient is a whole number, then 4 and 29,962,588.75 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 | 119,850,355 | |
| -1 | 119,850,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 359 | 1,795 | 2,903 | 8,257 | 14,515 | 41,285 | 66,769 | 333,845 | 1,042,177 | 5,210,885 | 23,970,071 | 119,850,355 |
| -1 | -5 | -23 | -115 | -359 | -1,795 | -2,903 | -8,257 | -14,515 | -41,285 | -66,769 | -333,845 | -1,042,177 | -5,210,885 | -23,970,071 | -119,850,355 |
