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 10,789,751, 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 | 10,789,751 | |
| -1 | -10,789,751 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,789,751.
Example:
1 x 10,789,751 = 10,789,751
and
-1 x -10,789,751 = 10,789,751
Notice both answers equal 10,789,751
With that explanation out of the way, let's continue. Next, we take the number 10,789,751 and divide it by 2:
10,789,751 ÷ 2 = 5,394,875.5
If the quotient is a whole number, then 2 and 5,394,875.5 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 | 10,789,751 | |
| -1 | -10,789,751 |
Now, we try dividing 10,789,751 by 3:
10,789,751 ÷ 3 = 3,596,583.6667
If the quotient is a whole number, then 3 and 3,596,583.6667 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 | 10,789,751 | |
| -1 | -10,789,751 |
Let's try dividing by 4:
10,789,751 ÷ 4 = 2,697,437.75
If the quotient is a whole number, then 4 and 2,697,437.75 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 | 10,789,751 | |
| -1 | 10,789,751 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 83 | 343 | 379 | 581 | 2,653 | 4,067 | 18,571 | 28,469 | 31,457 | 129,997 | 220,199 | 1,541,393 | 10,789,751 |
| -1 | -7 | -49 | -83 | -343 | -379 | -581 | -2,653 | -4,067 | -18,571 | -28,469 | -31,457 | -129,997 | -220,199 | -1,541,393 | -10,789,751 |
