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 20,142,023, 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 | 20,142,023 | |
| -1 | -20,142,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,142,023.
Example:
1 x 20,142,023 = 20,142,023
and
-1 x -20,142,023 = 20,142,023
Notice both answers equal 20,142,023
With that explanation out of the way, let's continue. Next, we take the number 20,142,023 and divide it by 2:
20,142,023 ÷ 2 = 10,071,011.5
If the quotient is a whole number, then 2 and 10,071,011.5 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 | 20,142,023 | |
| -1 | -20,142,023 |
Now, we try dividing 20,142,023 by 3:
20,142,023 ÷ 3 = 6,714,007.6667
If the quotient is a whole number, then 3 and 6,714,007.6667 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 | 20,142,023 | |
| -1 | -20,142,023 |
Let's try dividing by 4:
20,142,023 ÷ 4 = 5,035,505.75
If the quotient is a whole number, then 4 and 5,035,505.75 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 | 20,142,023 | |
| -1 | 20,142,023 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 121 | 407 | 409 | 1,331 | 4,477 | 4,499 | 15,133 | 49,247 | 49,489 | 166,463 | 544,379 | 1,831,093 | 20,142,023 |
| -1 | -11 | -37 | -121 | -407 | -409 | -1,331 | -4,477 | -4,499 | -15,133 | -49,247 | -49,489 | -166,463 | -544,379 | -1,831,093 | -20,142,023 |
