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 4,042,423, 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 | 4,042,423 | |
| -1 | -4,042,423 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,042,423.
Example:
1 x 4,042,423 = 4,042,423
and
-1 x -4,042,423 = 4,042,423
Notice both answers equal 4,042,423
With that explanation out of the way, let's continue. Next, we take the number 4,042,423 and divide it by 2:
4,042,423 ÷ 2 = 2,021,211.5
If the quotient is a whole number, then 2 and 2,021,211.5 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 | 4,042,423 | |
| -1 | -4,042,423 |
Now, we try dividing 4,042,423 by 3:
4,042,423 ÷ 3 = 1,347,474.3333
If the quotient is a whole number, then 3 and 1,347,474.3333 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 | 4,042,423 | |
| -1 | -4,042,423 |
Let's try dividing by 4:
4,042,423 ÷ 4 = 1,010,605.75
If the quotient is a whole number, then 4 and 1,010,605.75 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 | 4,042,423 | |
| -1 | 4,042,423 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 47 | 77 | 329 | 517 | 1,117 | 3,619 | 7,819 | 12,287 | 52,499 | 86,009 | 367,493 | 577,489 | 4,042,423 |
| -1 | -7 | -11 | -47 | -77 | -329 | -517 | -1,117 | -3,619 | -7,819 | -12,287 | -52,499 | -86,009 | -367,493 | -577,489 | -4,042,423 |
