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 121,127,633, 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 | 121,127,633 | |
| -1 | -121,127,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,127,633.
Example:
1 x 121,127,633 = 121,127,633
and
-1 x -121,127,633 = 121,127,633
Notice both answers equal 121,127,633
With that explanation out of the way, let's continue. Next, we take the number 121,127,633 and divide it by 2:
121,127,633 ÷ 2 = 60,563,816.5
If the quotient is a whole number, then 2 and 60,563,816.5 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 | 121,127,633 | |
| -1 | -121,127,633 |
Now, we try dividing 121,127,633 by 3:
121,127,633 ÷ 3 = 40,375,877.6667
If the quotient is a whole number, then 3 and 40,375,877.6667 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 | 121,127,633 | |
| -1 | -121,127,633 |
Let's try dividing by 4:
121,127,633 ÷ 4 = 30,281,908.25
If the quotient is a whole number, then 4 and 30,281,908.25 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 | 121,127,633 | |
| -1 | 121,127,633 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 71 | 341 | 781 | 2,201 | 5,003 | 24,211 | 55,033 | 155,093 | 355,213 | 1,706,023 | 3,907,343 | 11,011,603 | 121,127,633 |
| -1 | -11 | -31 | -71 | -341 | -781 | -2,201 | -5,003 | -24,211 | -55,033 | -155,093 | -355,213 | -1,706,023 | -3,907,343 | -11,011,603 | -121,127,633 |
