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 121,483,033, 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 | 121,483,033 | |
| -1 | -121,483,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,483,033.
Example:
1 x 121,483,033 = 121,483,033
and
-1 x -121,483,033 = 121,483,033
Notice both answers equal 121,483,033
With that explanation out of the way, let's continue. Next, we take the number 121,483,033 and divide it by 2:
121,483,033 ÷ 2 = 60,741,516.5
If the quotient is a whole number, then 2 and 60,741,516.5 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 | 121,483,033 | |
| -1 | -121,483,033 |
Now, we try dividing 121,483,033 by 3:
121,483,033 ÷ 3 = 40,494,344.3333
If the quotient is a whole number, then 3 and 40,494,344.3333 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 | 121,483,033 | |
| -1 | -121,483,033 |
Let's try dividing by 4:
121,483,033 ÷ 4 = 30,370,758.25
If the quotient is a whole number, then 4 and 30,370,758.25 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 | 121,483,033 | |
| -1 | 121,483,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 83 | 161 | 581 | 1,909 | 9,091 | 13,363 | 63,637 | 209,093 | 754,553 | 1,463,651 | 5,281,871 | 17,354,719 | 121,483,033 |
| -1 | -7 | -23 | -83 | -161 | -581 | -1,909 | -9,091 | -13,363 | -63,637 | -209,093 | -754,553 | -1,463,651 | -5,281,871 | -17,354,719 | -121,483,033 |
