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 10,516,705, 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 | 10,516,705 | |
| -1 | -10,516,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,516,705.
Example:
1 x 10,516,705 = 10,516,705
and
-1 x -10,516,705 = 10,516,705
Notice both answers equal 10,516,705
With that explanation out of the way, let's continue. Next, we take the number 10,516,705 and divide it by 2:
10,516,705 ÷ 2 = 5,258,352.5
If the quotient is a whole number, then 2 and 5,258,352.5 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 | 10,516,705 | |
| -1 | -10,516,705 |
Now, we try dividing 10,516,705 by 3:
10,516,705 ÷ 3 = 3,505,568.3333
If the quotient is a whole number, then 3 and 3,505,568.3333 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 | 10,516,705 | |
| -1 | -10,516,705 |
Let's try dividing by 4:
10,516,705 ÷ 4 = 2,629,176.25
If the quotient is a whole number, then 4 and 2,629,176.25 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 | 10,516,705 | |
| -1 | 10,516,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 61 | 145 | 205 | 305 | 841 | 1,189 | 1,769 | 2,501 | 4,205 | 5,945 | 8,845 | 12,505 | 34,481 | 51,301 | 72,529 | 172,405 | 256,505 | 362,645 | 2,103,341 | 10,516,705 |
| -1 | -5 | -29 | -41 | -61 | -145 | -205 | -305 | -841 | -1,189 | -1,769 | -2,501 | -4,205 | -5,945 | -8,845 | -12,505 | -34,481 | -51,301 | -72,529 | -172,405 | -256,505 | -362,645 | -2,103,341 | -10,516,705 |
