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 833,664,121, 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 | 833,664,121 | |
| -1 | -833,664,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 833,664,121.
Example:
1 x 833,664,121 = 833,664,121
and
-1 x -833,664,121 = 833,664,121
Notice both answers equal 833,664,121
With that explanation out of the way, let's continue. Next, we take the number 833,664,121 and divide it by 2:
833,664,121 ÷ 2 = 416,832,060.5
If the quotient is a whole number, then 2 and 416,832,060.5 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 | 833,664,121 | |
| -1 | -833,664,121 |
Now, we try dividing 833,664,121 by 3:
833,664,121 ÷ 3 = 277,888,040.3333
If the quotient is a whole number, then 3 and 277,888,040.3333 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 | 833,664,121 | |
| -1 | -833,664,121 |
Let's try dividing by 4:
833,664,121 ÷ 4 = 208,416,030.25
If the quotient is a whole number, then 4 and 208,416,030.25 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 | 833,664,121 | |
| -1 | 833,664,121 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 251 | 589 | 4,769 | 5,639 | 7,781 | 107,141 | 147,839 | 174,809 | 1,415,389 | 3,321,371 | 26,892,391 | 43,877,059 | 833,664,121 |
| -1 | -19 | -31 | -251 | -589 | -4,769 | -5,639 | -7,781 | -107,141 | -147,839 | -174,809 | -1,415,389 | -3,321,371 | -26,892,391 | -43,877,059 | -833,664,121 |
