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 351,115,105, 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 | 351,115,105 | |
| -1 | -351,115,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 351,115,105.
Example:
1 x 351,115,105 = 351,115,105
and
-1 x -351,115,105 = 351,115,105
Notice both answers equal 351,115,105
With that explanation out of the way, let's continue. Next, we take the number 351,115,105 and divide it by 2:
351,115,105 ÷ 2 = 175,557,552.5
If the quotient is a whole number, then 2 and 175,557,552.5 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 | 351,115,105 | |
| -1 | -351,115,105 |
Now, we try dividing 351,115,105 by 3:
351,115,105 ÷ 3 = 117,038,368.3333
If the quotient is a whole number, then 3 and 117,038,368.3333 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 | 351,115,105 | |
| -1 | -351,115,105 |
Let's try dividing by 4:
351,115,105 ÷ 4 = 87,778,776.25
If the quotient is a whole number, then 4 and 87,778,776.25 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 | 351,115,105 | |
| -1 | 351,115,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 79 | 395 | 869 | 4,345 | 80,809 | 404,045 | 888,899 | 4,444,495 | 6,383,911 | 31,919,555 | 70,223,021 | 351,115,105 |
| -1 | -5 | -11 | -55 | -79 | -395 | -869 | -4,345 | -80,809 | -404,045 | -888,899 | -4,444,495 | -6,383,911 | -31,919,555 | -70,223,021 | -351,115,105 |
