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 22,678,117, 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 | 22,678,117 | |
| -1 | -22,678,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,678,117.
Example:
1 x 22,678,117 = 22,678,117
and
-1 x -22,678,117 = 22,678,117
Notice both answers equal 22,678,117
With that explanation out of the way, let's continue. Next, we take the number 22,678,117 and divide it by 2:
22,678,117 ÷ 2 = 11,339,058.5
If the quotient is a whole number, then 2 and 11,339,058.5 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 | 22,678,117 | |
| -1 | -22,678,117 |
Now, we try dividing 22,678,117 by 3:
22,678,117 ÷ 3 = 7,559,372.3333
If the quotient is a whole number, then 3 and 7,559,372.3333 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 | 22,678,117 | |
| -1 | -22,678,117 |
Let's try dividing by 4:
22,678,117 ÷ 4 = 5,669,529.25
If the quotient is a whole number, then 4 and 5,669,529.25 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 | 22,678,117 | |
| -1 | 22,678,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 53 | 77 | 371 | 583 | 4,081 | 5,557 | 38,899 | 61,127 | 294,521 | 427,889 | 2,061,647 | 3,239,731 | 22,678,117 |
| -1 | -7 | -11 | -53 | -77 | -371 | -583 | -4,081 | -5,557 | -38,899 | -61,127 | -294,521 | -427,889 | -2,061,647 | -3,239,731 | -22,678,117 |
