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 10,422,815, 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 | 10,422,815 | |
| -1 | -10,422,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,422,815.
Example:
1 x 10,422,815 = 10,422,815
and
-1 x -10,422,815 = 10,422,815
Notice both answers equal 10,422,815
With that explanation out of the way, let's continue. Next, we take the number 10,422,815 and divide it by 2:
10,422,815 ÷ 2 = 5,211,407.5
If the quotient is a whole number, then 2 and 5,211,407.5 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 | 10,422,815 | |
| -1 | -10,422,815 |
Now, we try dividing 10,422,815 by 3:
10,422,815 ÷ 3 = 3,474,271.6667
If the quotient is a whole number, then 3 and 3,474,271.6667 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 | 10,422,815 | |
| -1 | -10,422,815 |
Let's try dividing by 4:
10,422,815 ÷ 4 = 2,605,703.75
If the quotient is a whole number, then 4 and 2,605,703.75 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 | 10,422,815 | |
| -1 | 10,422,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 41 | 65 | 205 | 533 | 2,665 | 3,911 | 19,555 | 50,843 | 160,351 | 254,215 | 801,755 | 2,084,563 | 10,422,815 |
| -1 | -5 | -13 | -41 | -65 | -205 | -533 | -2,665 | -3,911 | -19,555 | -50,843 | -160,351 | -254,215 | -801,755 | -2,084,563 | -10,422,815 |
