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 26,132,771, 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 | 26,132,771 | |
| -1 | -26,132,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,132,771.
Example:
1 x 26,132,771 = 26,132,771
and
-1 x -26,132,771 = 26,132,771
Notice both answers equal 26,132,771
With that explanation out of the way, let's continue. Next, we take the number 26,132,771 and divide it by 2:
26,132,771 ÷ 2 = 13,066,385.5
If the quotient is a whole number, then 2 and 13,066,385.5 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 | 26,132,771 | |
| -1 | -26,132,771 |
Now, we try dividing 26,132,771 by 3:
26,132,771 ÷ 3 = 8,710,923.6667
If the quotient is a whole number, then 3 and 8,710,923.6667 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 | 26,132,771 | |
| -1 | -26,132,771 |
Let's try dividing by 4:
26,132,771 ÷ 4 = 6,533,192.75
If the quotient is a whole number, then 4 and 6,533,192.75 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 | 26,132,771 | |
| -1 | 26,132,771 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 349 | 563 | 2,443 | 3,941 | 6,631 | 10,697 | 46,417 | 74,879 | 196,487 | 1,375,409 | 3,733,253 | 26,132,771 |
| -1 | -7 | -19 | -133 | -349 | -563 | -2,443 | -3,941 | -6,631 | -10,697 | -46,417 | -74,879 | -196,487 | -1,375,409 | -3,733,253 | -26,132,771 |
