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 26,424,079, 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 | 26,424,079 | |
| -1 | -26,424,079 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,424,079.
Example:
1 x 26,424,079 = 26,424,079
and
-1 x -26,424,079 = 26,424,079
Notice both answers equal 26,424,079
With that explanation out of the way, let's continue. Next, we take the number 26,424,079 and divide it by 2:
26,424,079 ÷ 2 = 13,212,039.5
If the quotient is a whole number, then 2 and 13,212,039.5 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 | 26,424,079 | |
| -1 | -26,424,079 |
Now, we try dividing 26,424,079 by 3:
26,424,079 ÷ 3 = 8,808,026.3333
If the quotient is a whole number, then 3 and 8,808,026.3333 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 | 26,424,079 | |
| -1 | -26,424,079 |
Let's try dividing by 4:
26,424,079 ÷ 4 = 6,606,019.75
If the quotient is a whole number, then 4 and 6,606,019.75 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 | 26,424,079 | |
| -1 | 26,424,079 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 239 | 253 | 437 | 529 | 2,629 | 4,541 | 4,807 | 5,497 | 5,819 | 10,051 | 49,951 | 60,467 | 104,443 | 110,561 | 126,431 | 1,148,873 | 1,390,741 | 2,402,189 | 26,424,079 |
| -1 | -11 | -19 | -23 | -209 | -239 | -253 | -437 | -529 | -2,629 | -4,541 | -4,807 | -5,497 | -5,819 | -10,051 | -49,951 | -60,467 | -104,443 | -110,561 | -126,431 | -1,148,873 | -1,390,741 | -2,402,189 | -26,424,079 |
