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 26,356,265, 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 | 26,356,265 | |
| -1 | -26,356,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,356,265.
Example:
1 x 26,356,265 = 26,356,265
and
-1 x -26,356,265 = 26,356,265
Notice both answers equal 26,356,265
With that explanation out of the way, let's continue. Next, we take the number 26,356,265 and divide it by 2:
26,356,265 ÷ 2 = 13,178,132.5
If the quotient is a whole number, then 2 and 13,178,132.5 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 | 26,356,265 | |
| -1 | -26,356,265 |
Now, we try dividing 26,356,265 by 3:
26,356,265 ÷ 3 = 8,785,421.6667
If the quotient is a whole number, then 3 and 8,785,421.6667 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 | 26,356,265 | |
| -1 | -26,356,265 |
Let's try dividing by 4:
26,356,265 ÷ 4 = 6,589,066.25
If the quotient is a whole number, then 4 and 6,589,066.25 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 | 26,356,265 | |
| -1 | 26,356,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 71 | 355 | 923 | 4,615 | 5,711 | 28,555 | 74,243 | 371,215 | 405,481 | 2,027,405 | 5,271,253 | 26,356,265 |
| -1 | -5 | -13 | -65 | -71 | -355 | -923 | -4,615 | -5,711 | -28,555 | -74,243 | -371,215 | -405,481 | -2,027,405 | -5,271,253 | -26,356,265 |
