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 4,026,127, 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 | 4,026,127 | |
| -1 | -4,026,127 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,026,127.
Example:
1 x 4,026,127 = 4,026,127
and
-1 x -4,026,127 = 4,026,127
Notice both answers equal 4,026,127
With that explanation out of the way, let's continue. Next, we take the number 4,026,127 and divide it by 2:
4,026,127 ÷ 2 = 2,013,063.5
If the quotient is a whole number, then 2 and 2,013,063.5 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 | 4,026,127 | |
| -1 | -4,026,127 |
Now, we try dividing 4,026,127 by 3:
4,026,127 ÷ 3 = 1,342,042.3333
If the quotient is a whole number, then 3 and 1,342,042.3333 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 | 4,026,127 | |
| -1 | -4,026,127 |
Let's try dividing by 4:
4,026,127 ÷ 4 = 1,006,531.75
If the quotient is a whole number, then 4 and 1,006,531.75 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 | 4,026,127 | |
| -1 | 4,026,127 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 23 | 119 | 161 | 391 | 1,471 | 2,737 | 10,297 | 25,007 | 33,833 | 175,049 | 236,831 | 575,161 | 4,026,127 |
| -1 | -7 | -17 | -23 | -119 | -161 | -391 | -1,471 | -2,737 | -10,297 | -25,007 | -33,833 | -175,049 | -236,831 | -575,161 | -4,026,127 |
