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 105,156,115, 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 | 105,156,115 | |
| -1 | -105,156,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,156,115.
Example:
1 x 105,156,115 = 105,156,115
and
-1 x -105,156,115 = 105,156,115
Notice both answers equal 105,156,115
With that explanation out of the way, let's continue. Next, we take the number 105,156,115 and divide it by 2:
105,156,115 ÷ 2 = 52,578,057.5
If the quotient is a whole number, then 2 and 52,578,057.5 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 | 105,156,115 | |
| -1 | -105,156,115 |
Now, we try dividing 105,156,115 by 3:
105,156,115 ÷ 3 = 35,052,038.3333
If the quotient is a whole number, then 3 and 35,052,038.3333 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 | 105,156,115 | |
| -1 | -105,156,115 |
Let's try dividing by 4:
105,156,115 ÷ 4 = 26,289,028.75
If the quotient is a whole number, then 4 and 26,289,028.75 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 | 105,156,115 | |
| -1 | 105,156,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 109 | 115 | 545 | 2,507 | 8,389 | 12,535 | 41,945 | 192,947 | 914,401 | 964,735 | 4,572,005 | 21,031,223 | 105,156,115 |
| -1 | -5 | -23 | -109 | -115 | -545 | -2,507 | -8,389 | -12,535 | -41,945 | -192,947 | -914,401 | -964,735 | -4,572,005 | -21,031,223 | -105,156,115 |
