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 16,340,023, 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 | 16,340,023 | |
| -1 | -16,340,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,340,023.
Example:
1 x 16,340,023 = 16,340,023
and
-1 x -16,340,023 = 16,340,023
Notice both answers equal 16,340,023
With that explanation out of the way, let's continue. Next, we take the number 16,340,023 and divide it by 2:
16,340,023 ÷ 2 = 8,170,011.5
If the quotient is a whole number, then 2 and 8,170,011.5 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 | 16,340,023 | |
| -1 | -16,340,023 |
Now, we try dividing 16,340,023 by 3:
16,340,023 ÷ 3 = 5,446,674.3333
If the quotient is a whole number, then 3 and 5,446,674.3333 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 | 16,340,023 | |
| -1 | -16,340,023 |
Let's try dividing by 4:
16,340,023 ÷ 4 = 4,085,005.75
If the quotient is a whole number, then 4 and 4,085,005.75 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 | 16,340,023 | |
| -1 | 16,340,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 131 | 173 | 721 | 917 | 1,211 | 13,493 | 17,819 | 22,663 | 94,451 | 124,733 | 158,641 | 2,334,289 | 16,340,023 |
| -1 | -7 | -103 | -131 | -173 | -721 | -917 | -1,211 | -13,493 | -17,819 | -22,663 | -94,451 | -124,733 | -158,641 | -2,334,289 | -16,340,023 |
