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 6,386,135, 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 | 6,386,135 | |
| -1 | -6,386,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,386,135.
Example:
1 x 6,386,135 = 6,386,135
and
-1 x -6,386,135 = 6,386,135
Notice both answers equal 6,386,135
With that explanation out of the way, let's continue. Next, we take the number 6,386,135 and divide it by 2:
6,386,135 ÷ 2 = 3,193,067.5
If the quotient is a whole number, then 2 and 3,193,067.5 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 | 6,386,135 | |
| -1 | -6,386,135 |
Now, we try dividing 6,386,135 by 3:
6,386,135 ÷ 3 = 2,128,711.6667
If the quotient is a whole number, then 3 and 2,128,711.6667 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 | 6,386,135 | |
| -1 | -6,386,135 |
Let's try dividing by 4:
6,386,135 ÷ 4 = 1,596,533.75
If the quotient is a whole number, then 4 and 1,596,533.75 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 | 6,386,135 | |
| -1 | 6,386,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 10,733 | 53,665 | 75,131 | 182,461 | 375,655 | 912,305 | 1,277,227 | 6,386,135 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -10,733 | -53,665 | -75,131 | -182,461 | -375,655 | -912,305 | -1,277,227 | -6,386,135 |
