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 12,035,023, 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 | 12,035,023 | |
| -1 | -12,035,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,035,023.
Example:
1 x 12,035,023 = 12,035,023
and
-1 x -12,035,023 = 12,035,023
Notice both answers equal 12,035,023
With that explanation out of the way, let's continue. Next, we take the number 12,035,023 and divide it by 2:
12,035,023 ÷ 2 = 6,017,511.5
If the quotient is a whole number, then 2 and 6,017,511.5 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 | 12,035,023 | |
| -1 | -12,035,023 |
Now, we try dividing 12,035,023 by 3:
12,035,023 ÷ 3 = 4,011,674.3333
If the quotient is a whole number, then 3 and 4,011,674.3333 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 | 12,035,023 | |
| -1 | -12,035,023 |
Let's try dividing by 4:
12,035,023 ÷ 4 = 3,008,755.75
If the quotient is a whole number, then 4 and 3,008,755.75 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 | 12,035,023 | |
| -1 | 12,035,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 143 | 847 | 1,001 | 1,093 | 1,573 | 7,651 | 11,011 | 12,023 | 14,209 | 84,161 | 99,463 | 132,253 | 156,299 | 925,771 | 1,094,093 | 1,719,289 | 12,035,023 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -143 | -847 | -1,001 | -1,093 | -1,573 | -7,651 | -11,011 | -12,023 | -14,209 | -84,161 | -99,463 | -132,253 | -156,299 | -925,771 | -1,094,093 | -1,719,289 | -12,035,023 |
