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 10,422,887, 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 | 10,422,887 | |
| -1 | -10,422,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,422,887.
Example:
1 x 10,422,887 = 10,422,887
and
-1 x -10,422,887 = 10,422,887
Notice both answers equal 10,422,887
With that explanation out of the way, let's continue. Next, we take the number 10,422,887 and divide it by 2:
10,422,887 ÷ 2 = 5,211,443.5
If the quotient is a whole number, then 2 and 5,211,443.5 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 | 10,422,887 | |
| -1 | -10,422,887 |
Now, we try dividing 10,422,887 by 3:
10,422,887 ÷ 3 = 3,474,295.6667
If the quotient is a whole number, then 3 and 3,474,295.6667 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 | 10,422,887 | |
| -1 | -10,422,887 |
Let's try dividing by 4:
10,422,887 ÷ 4 = 2,605,721.75
If the quotient is a whole number, then 4 and 2,605,721.75 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 | 10,422,887 | |
| -1 | 10,422,887 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 23 | 61 | 323 | 391 | 437 | 529 | 1,037 | 1,159 | 1,403 | 7,429 | 8,993 | 10,051 | 19,703 | 23,851 | 26,657 | 32,269 | 170,867 | 453,169 | 548,573 | 613,111 | 10,422,887 |
| -1 | -17 | -19 | -23 | -61 | -323 | -391 | -437 | -529 | -1,037 | -1,159 | -1,403 | -7,429 | -8,993 | -10,051 | -19,703 | -23,851 | -26,657 | -32,269 | -170,867 | -453,169 | -548,573 | -613,111 | -10,422,887 |
