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 22,061,377, 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 | 22,061,377 | |
| -1 | -22,061,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,061,377.
Example:
1 x 22,061,377 = 22,061,377
and
-1 x -22,061,377 = 22,061,377
Notice both answers equal 22,061,377
With that explanation out of the way, let's continue. Next, we take the number 22,061,377 and divide it by 2:
22,061,377 ÷ 2 = 11,030,688.5
If the quotient is a whole number, then 2 and 11,030,688.5 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 | 22,061,377 | |
| -1 | -22,061,377 |
Now, we try dividing 22,061,377 by 3:
22,061,377 ÷ 3 = 7,353,792.3333
If the quotient is a whole number, then 3 and 7,353,792.3333 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 | 22,061,377 | |
| -1 | -22,061,377 |
Let's try dividing by 4:
22,061,377 ÷ 4 = 5,515,344.25
If the quotient is a whole number, then 4 and 5,515,344.25 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 | 22,061,377 | |
| -1 | 22,061,377 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 611 | 36,107 | 469,391 | 1,697,029 | 22,061,377 |
| -1 | -13 | -47 | -611 | -36,107 | -469,391 | -1,697,029 | -22,061,377 |
