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 116,020,201, 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 | 116,020,201 | |
| -1 | -116,020,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,020,201.
Example:
1 x 116,020,201 = 116,020,201
and
-1 x -116,020,201 = 116,020,201
Notice both answers equal 116,020,201
With that explanation out of the way, let's continue. Next, we take the number 116,020,201 and divide it by 2:
116,020,201 ÷ 2 = 58,010,100.5
If the quotient is a whole number, then 2 and 58,010,100.5 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 | 116,020,201 | |
| -1 | -116,020,201 |
Now, we try dividing 116,020,201 by 3:
116,020,201 ÷ 3 = 38,673,400.3333
If the quotient is a whole number, then 3 and 38,673,400.3333 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 | 116,020,201 | |
| -1 | -116,020,201 |
Let's try dividing by 4:
116,020,201 ÷ 4 = 29,005,050.25
If the quotient is a whole number, then 4 and 29,005,050.25 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 | 116,020,201 | |
| -1 | 116,020,201 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 173 | 451 | 1,487 | 1,903 | 7,093 | 16,357 | 60,967 | 78,023 | 257,251 | 670,637 | 2,829,761 | 10,547,291 | 116,020,201 |
| -1 | -11 | -41 | -173 | -451 | -1,487 | -1,903 | -7,093 | -16,357 | -60,967 | -78,023 | -257,251 | -670,637 | -2,829,761 | -10,547,291 | -116,020,201 |
