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 20,446,223, 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 | 20,446,223 | |
| -1 | -20,446,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,446,223.
Example:
1 x 20,446,223 = 20,446,223
and
-1 x -20,446,223 = 20,446,223
Notice both answers equal 20,446,223
With that explanation out of the way, let's continue. Next, we take the number 20,446,223 and divide it by 2:
20,446,223 ÷ 2 = 10,223,111.5
If the quotient is a whole number, then 2 and 10,223,111.5 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 | 20,446,223 | |
| -1 | -20,446,223 |
Now, we try dividing 20,446,223 by 3:
20,446,223 ÷ 3 = 6,815,407.6667
If the quotient is a whole number, then 3 and 6,815,407.6667 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 | 20,446,223 | |
| -1 | -20,446,223 |
Let's try dividing by 4:
20,446,223 ÷ 4 = 5,111,555.75
If the quotient is a whole number, then 4 and 5,111,555.75 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 | 20,446,223 | |
| -1 | 20,446,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 9,043 | 63,301 | 153,731 | 171,817 | 1,076,117 | 1,202,719 | 2,920,889 | 20,446,223 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -9,043 | -63,301 | -153,731 | -171,817 | -1,076,117 | -1,202,719 | -2,920,889 | -20,446,223 |
