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 20,022,541, 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 | 20,022,541 | |
| -1 | -20,022,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,022,541.
Example:
1 x 20,022,541 = 20,022,541
and
-1 x -20,022,541 = 20,022,541
Notice both answers equal 20,022,541
With that explanation out of the way, let's continue. Next, we take the number 20,022,541 and divide it by 2:
20,022,541 ÷ 2 = 10,011,270.5
If the quotient is a whole number, then 2 and 10,011,270.5 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 | 20,022,541 | |
| -1 | -20,022,541 |
Now, we try dividing 20,022,541 by 3:
20,022,541 ÷ 3 = 6,674,180.3333
If the quotient is a whole number, then 3 and 6,674,180.3333 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 | 20,022,541 | |
| -1 | -20,022,541 |
Let's try dividing by 4:
20,022,541 ÷ 4 = 5,005,635.25
If the quotient is a whole number, then 4 and 5,005,635.25 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 | 20,022,541 | |
| -1 | 20,022,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 457 | 569 | 3,199 | 3,983 | 5,027 | 6,259 | 35,189 | 43,813 | 260,033 | 1,820,231 | 2,860,363 | 20,022,541 |
| -1 | -7 | -11 | -77 | -457 | -569 | -3,199 | -3,983 | -5,027 | -6,259 | -35,189 | -43,813 | -260,033 | -1,820,231 | -2,860,363 | -20,022,541 |
