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 4,053,023, 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 | 4,053,023 | |
| -1 | -4,053,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,053,023.
Example:
1 x 4,053,023 = 4,053,023
and
-1 x -4,053,023 = 4,053,023
Notice both answers equal 4,053,023
With that explanation out of the way, let's continue. Next, we take the number 4,053,023 and divide it by 2:
4,053,023 ÷ 2 = 2,026,511.5
If the quotient is a whole number, then 2 and 2,026,511.5 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 | 4,053,023 | |
| -1 | -4,053,023 |
Now, we try dividing 4,053,023 by 3:
4,053,023 ÷ 3 = 1,351,007.6667
If the quotient is a whole number, then 3 and 1,351,007.6667 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 | 4,053,023 | |
| -1 | -4,053,023 |
Let's try dividing by 4:
4,053,023 ÷ 4 = 1,013,255.75
If the quotient is a whole number, then 4 and 1,013,255.75 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 | 4,053,023 | |
| -1 | 4,053,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 61 | 247 | 269 | 793 | 1,159 | 3,497 | 5,111 | 15,067 | 16,409 | 66,443 | 213,317 | 311,771 | 4,053,023 |
| -1 | -13 | -19 | -61 | -247 | -269 | -793 | -1,159 | -3,497 | -5,111 | -15,067 | -16,409 | -66,443 | -213,317 | -311,771 | -4,053,023 |
