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 22,361,647, 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 | 22,361,647 | |
| -1 | -22,361,647 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,361,647.
Example:
1 x 22,361,647 = 22,361,647
and
-1 x -22,361,647 = 22,361,647
Notice both answers equal 22,361,647
With that explanation out of the way, let's continue. Next, we take the number 22,361,647 and divide it by 2:
22,361,647 ÷ 2 = 11,180,823.5
If the quotient is a whole number, then 2 and 11,180,823.5 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 | 22,361,647 | |
| -1 | -22,361,647 |
Now, we try dividing 22,361,647 by 3:
22,361,647 ÷ 3 = 7,453,882.3333
If the quotient is a whole number, then 3 and 7,453,882.3333 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 | 22,361,647 | |
| -1 | -22,361,647 |
Let's try dividing by 4:
22,361,647 ÷ 4 = 5,590,411.75
If the quotient is a whole number, then 4 and 5,590,411.75 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 | 22,361,647 | |
| -1 | 22,361,647 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 121 | 187 | 847 | 1,309 | 1,553 | 2,057 | 10,871 | 14,399 | 17,083 | 26,401 | 119,581 | 184,807 | 187,913 | 290,411 | 1,315,391 | 2,032,877 | 3,194,521 | 22,361,647 |
| -1 | -7 | -11 | -17 | -77 | -119 | -121 | -187 | -847 | -1,309 | -1,553 | -2,057 | -10,871 | -14,399 | -17,083 | -26,401 | -119,581 | -184,807 | -187,913 | -290,411 | -1,315,391 | -2,032,877 | -3,194,521 | -22,361,647 |
