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 10,670,387, 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 | 10,670,387 | |
| -1 | -10,670,387 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,670,387.
Example:
1 x 10,670,387 = 10,670,387
and
-1 x -10,670,387 = 10,670,387
Notice both answers equal 10,670,387
With that explanation out of the way, let's continue. Next, we take the number 10,670,387 and divide it by 2:
10,670,387 ÷ 2 = 5,335,193.5
If the quotient is a whole number, then 2 and 5,335,193.5 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 | 10,670,387 | |
| -1 | -10,670,387 |
Now, we try dividing 10,670,387 by 3:
10,670,387 ÷ 3 = 3,556,795.6667
If the quotient is a whole number, then 3 and 3,556,795.6667 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 | 10,670,387 | |
| -1 | -10,670,387 |
Let's try dividing by 4:
10,670,387 ÷ 4 = 2,667,596.75
If the quotient is a whole number, then 4 and 2,667,596.75 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 | 10,670,387 | |
| -1 | 10,670,387 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 343 | 637 | 2,393 | 4,459 | 16,751 | 31,109 | 117,257 | 217,763 | 820,799 | 1,524,341 | 10,670,387 |
| -1 | -7 | -13 | -49 | -91 | -343 | -637 | -2,393 | -4,459 | -16,751 | -31,109 | -117,257 | -217,763 | -820,799 | -1,524,341 | -10,670,387 |
