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 26,240,123, 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 | 26,240,123 | |
| -1 | -26,240,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,240,123.
Example:
1 x 26,240,123 = 26,240,123
and
-1 x -26,240,123 = 26,240,123
Notice both answers equal 26,240,123
With that explanation out of the way, let's continue. Next, we take the number 26,240,123 and divide it by 2:
26,240,123 ÷ 2 = 13,120,061.5
If the quotient is a whole number, then 2 and 13,120,061.5 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 | 26,240,123 | |
| -1 | -26,240,123 |
Now, we try dividing 26,240,123 by 3:
26,240,123 ÷ 3 = 8,746,707.6667
If the quotient is a whole number, then 3 and 8,746,707.6667 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 | 26,240,123 | |
| -1 | -26,240,123 |
Let's try dividing by 4:
26,240,123 ÷ 4 = 6,560,030.75
If the quotient is a whole number, then 4 and 6,560,030.75 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 | 26,240,123 | |
| -1 | 26,240,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 91 | 169 | 287 | 533 | 541 | 1,183 | 3,731 | 3,787 | 6,929 | 7,033 | 22,181 | 48,503 | 49,231 | 91,429 | 155,267 | 288,353 | 640,003 | 2,018,471 | 3,748,589 | 26,240,123 |
| -1 | -7 | -13 | -41 | -91 | -169 | -287 | -533 | -541 | -1,183 | -3,731 | -3,787 | -6,929 | -7,033 | -22,181 | -48,503 | -49,231 | -91,429 | -155,267 | -288,353 | -640,003 | -2,018,471 | -3,748,589 | -26,240,123 |
