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 26,066,705, 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 | 26,066,705 | |
| -1 | -26,066,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,066,705.
Example:
1 x 26,066,705 = 26,066,705
and
-1 x -26,066,705 = 26,066,705
Notice both answers equal 26,066,705
With that explanation out of the way, let's continue. Next, we take the number 26,066,705 and divide it by 2:
26,066,705 ÷ 2 = 13,033,352.5
If the quotient is a whole number, then 2 and 13,033,352.5 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 | 26,066,705 | |
| -1 | -26,066,705 |
Now, we try dividing 26,066,705 by 3:
26,066,705 ÷ 3 = 8,688,901.6667
If the quotient is a whole number, then 3 and 8,688,901.6667 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 | 26,066,705 | |
| -1 | -26,066,705 |
Let's try dividing by 4:
26,066,705 ÷ 4 = 6,516,676.25
If the quotient is a whole number, then 4 and 6,516,676.25 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 | 26,066,705 | |
| -1 | 26,066,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 32,381 | 161,905 | 226,667 | 744,763 | 1,133,335 | 3,723,815 | 5,213,341 | 26,066,705 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -32,381 | -161,905 | -226,667 | -744,763 | -1,133,335 | -3,723,815 | -5,213,341 | -26,066,705 |
