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 121,163,539, 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 | 121,163,539 | |
| -1 | -121,163,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,163,539.
Example:
1 x 121,163,539 = 121,163,539
and
-1 x -121,163,539 = 121,163,539
Notice both answers equal 121,163,539
With that explanation out of the way, let's continue. Next, we take the number 121,163,539 and divide it by 2:
121,163,539 ÷ 2 = 60,581,769.5
If the quotient is a whole number, then 2 and 60,581,769.5 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 | 121,163,539 | |
| -1 | -121,163,539 |
Now, we try dividing 121,163,539 by 3:
121,163,539 ÷ 3 = 40,387,846.3333
If the quotient is a whole number, then 3 and 40,387,846.3333 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 | 121,163,539 | |
| -1 | -121,163,539 |
Let's try dividing by 4:
121,163,539 ÷ 4 = 30,290,884.75
If the quotient is a whole number, then 4 and 30,290,884.75 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 | 121,163,539 | |
| -1 | 121,163,539 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 101 | 119 | 289 | 593 | 707 | 1,717 | 2,023 | 4,151 | 10,081 | 12,019 | 29,189 | 59,893 | 70,567 | 171,377 | 204,323 | 419,251 | 1,018,181 | 1,199,639 | 7,127,267 | 17,309,077 | 121,163,539 |
| -1 | -7 | -17 | -101 | -119 | -289 | -593 | -707 | -1,717 | -2,023 | -4,151 | -10,081 | -12,019 | -29,189 | -59,893 | -70,567 | -171,377 | -204,323 | -419,251 | -1,018,181 | -1,199,639 | -7,127,267 | -17,309,077 | -121,163,539 |
