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 121,032,095, 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 | 121,032,095 | |
| -1 | -121,032,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,032,095.
Example:
1 x 121,032,095 = 121,032,095
and
-1 x -121,032,095 = 121,032,095
Notice both answers equal 121,032,095
With that explanation out of the way, let's continue. Next, we take the number 121,032,095 and divide it by 2:
121,032,095 ÷ 2 = 60,516,047.5
If the quotient is a whole number, then 2 and 60,516,047.5 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 | 121,032,095 | |
| -1 | -121,032,095 |
Now, we try dividing 121,032,095 by 3:
121,032,095 ÷ 3 = 40,344,031.6667
If the quotient is a whole number, then 3 and 40,344,031.6667 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 | 121,032,095 | |
| -1 | -121,032,095 |
Let's try dividing by 4:
121,032,095 ÷ 4 = 30,258,023.75
If the quotient is a whole number, then 4 and 30,258,023.75 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 | 121,032,095 | |
| -1 | 121,032,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 61,909 | 309,545 | 1,052,453 | 1,423,907 | 5,262,265 | 7,119,535 | 24,206,419 | 121,032,095 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -61,909 | -309,545 | -1,052,453 | -1,423,907 | -5,262,265 | -7,119,535 | -24,206,419 | -121,032,095 |
