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 4,042,043, 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 | 4,042,043 | |
| -1 | -4,042,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,042,043.
Example:
1 x 4,042,043 = 4,042,043
and
-1 x -4,042,043 = 4,042,043
Notice both answers equal 4,042,043
With that explanation out of the way, let's continue. Next, we take the number 4,042,043 and divide it by 2:
4,042,043 ÷ 2 = 2,021,021.5
If the quotient is a whole number, then 2 and 2,021,021.5 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 | 4,042,043 | |
| -1 | -4,042,043 |
Now, we try dividing 4,042,043 by 3:
4,042,043 ÷ 3 = 1,347,347.6667
If the quotient is a whole number, then 3 and 1,347,347.6667 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 | 4,042,043 | |
| -1 | -4,042,043 |
Let's try dividing by 4:
4,042,043 ÷ 4 = 1,010,510.75
If the quotient is a whole number, then 4 and 1,010,510.75 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 | 4,042,043 | |
| -1 | 4,042,043 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 61 | 67 | 989 | 1,403 | 1,541 | 2,623 | 2,881 | 4,087 | 60,329 | 66,263 | 94,001 | 175,741 | 4,042,043 |
| -1 | -23 | -43 | -61 | -67 | -989 | -1,403 | -1,541 | -2,623 | -2,881 | -4,087 | -60,329 | -66,263 | -94,001 | -175,741 | -4,042,043 |
