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 122,213,333, 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 | 122,213,333 | |
| -1 | -122,213,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,213,333.
Example:
1 x 122,213,333 = 122,213,333
and
-1 x -122,213,333 = 122,213,333
Notice both answers equal 122,213,333
With that explanation out of the way, let's continue. Next, we take the number 122,213,333 and divide it by 2:
122,213,333 ÷ 2 = 61,106,666.5
If the quotient is a whole number, then 2 and 61,106,666.5 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 | 122,213,333 | |
| -1 | -122,213,333 |
Now, we try dividing 122,213,333 by 3:
122,213,333 ÷ 3 = 40,737,777.6667
If the quotient is a whole number, then 3 and 40,737,777.6667 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 | 122,213,333 | |
| -1 | -122,213,333 |
Let's try dividing by 4:
122,213,333 ÷ 4 = 30,553,333.25
If the quotient is a whole number, then 4 and 30,553,333.25 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 | 122,213,333 | |
| -1 | 122,213,333 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 101 | 451 | 1,111 | 2,683 | 4,141 | 29,513 | 45,551 | 110,003 | 270,983 | 1,210,033 | 2,980,813 | 11,110,303 | 122,213,333 |
| -1 | -11 | -41 | -101 | -451 | -1,111 | -2,683 | -4,141 | -29,513 | -45,551 | -110,003 | -270,983 | -1,210,033 | -2,980,813 | -11,110,303 | -122,213,333 |
