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 20,022,233, 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 | 20,022,233 | |
| -1 | -20,022,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,022,233.
Example:
1 x 20,022,233 = 20,022,233
and
-1 x -20,022,233 = 20,022,233
Notice both answers equal 20,022,233
With that explanation out of the way, let's continue. Next, we take the number 20,022,233 and divide it by 2:
20,022,233 ÷ 2 = 10,011,116.5
If the quotient is a whole number, then 2 and 10,011,116.5 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 | 20,022,233 | |
| -1 | -20,022,233 |
Now, we try dividing 20,022,233 by 3:
20,022,233 ÷ 3 = 6,674,077.6667
If the quotient is a whole number, then 3 and 6,674,077.6667 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 | 20,022,233 | |
| -1 | -20,022,233 |
Let's try dividing by 4:
20,022,233 ÷ 4 = 5,005,558.25
If the quotient is a whole number, then 4 and 5,005,558.25 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 | 20,022,233 | |
| -1 | 20,022,233 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 121 | 307 | 539 | 847 | 1,331 | 2,149 | 3,377 | 5,929 | 9,317 | 15,043 | 23,639 | 37,147 | 65,219 | 165,473 | 260,029 | 408,617 | 1,820,203 | 2,860,319 | 20,022,233 |
| -1 | -7 | -11 | -49 | -77 | -121 | -307 | -539 | -847 | -1,331 | -2,149 | -3,377 | -5,929 | -9,317 | -15,043 | -23,639 | -37,147 | -65,219 | -165,473 | -260,029 | -408,617 | -1,820,203 | -2,860,319 | -20,022,233 |
