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 26,402,495, 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 | 26,402,495 | |
| -1 | -26,402,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,402,495.
Example:
1 x 26,402,495 = 26,402,495
and
-1 x -26,402,495 = 26,402,495
Notice both answers equal 26,402,495
With that explanation out of the way, let's continue. Next, we take the number 26,402,495 and divide it by 2:
26,402,495 ÷ 2 = 13,201,247.5
If the quotient is a whole number, then 2 and 13,201,247.5 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 | 26,402,495 | |
| -1 | -26,402,495 |
Now, we try dividing 26,402,495 by 3:
26,402,495 ÷ 3 = 8,800,831.6667
If the quotient is a whole number, then 3 and 8,800,831.6667 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 | 26,402,495 | |
| -1 | -26,402,495 |
Let's try dividing by 4:
26,402,495 ÷ 4 = 6,600,623.75
If the quotient is a whole number, then 4 and 6,600,623.75 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 | 26,402,495 | |
| -1 | 26,402,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 39,703 | 198,515 | 277,921 | 754,357 | 1,389,605 | 3,771,785 | 5,280,499 | 26,402,495 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -39,703 | -198,515 | -277,921 | -754,357 | -1,389,605 | -3,771,785 | -5,280,499 | -26,402,495 |
