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 22,041,877, 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 | 22,041,877 | |
| -1 | -22,041,877 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,041,877.
Example:
1 x 22,041,877 = 22,041,877
and
-1 x -22,041,877 = 22,041,877
Notice both answers equal 22,041,877
With that explanation out of the way, let's continue. Next, we take the number 22,041,877 and divide it by 2:
22,041,877 ÷ 2 = 11,020,938.5
If the quotient is a whole number, then 2 and 11,020,938.5 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 | 22,041,877 | |
| -1 | -22,041,877 |
Now, we try dividing 22,041,877 by 3:
22,041,877 ÷ 3 = 7,347,292.3333
If the quotient is a whole number, then 3 and 7,347,292.3333 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 | 22,041,877 | |
| -1 | -22,041,877 |
Let's try dividing by 4:
22,041,877 ÷ 4 = 5,510,469.25
If the quotient is a whole number, then 4 and 5,510,469.25 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 | 22,041,877 | |
| -1 | 22,041,877 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 2,431 | 9,067 | 99,737 | 117,871 | 154,139 | 1,296,581 | 1,695,529 | 2,003,807 | 22,041,877 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -2,431 | -9,067 | -99,737 | -117,871 | -154,139 | -1,296,581 | -1,695,529 | -2,003,807 | -22,041,877 |
