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 26,814,491, 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 | 26,814,491 | |
| -1 | -26,814,491 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,814,491.
Example:
1 x 26,814,491 = 26,814,491
and
-1 x -26,814,491 = 26,814,491
Notice both answers equal 26,814,491
With that explanation out of the way, let's continue. Next, we take the number 26,814,491 and divide it by 2:
26,814,491 ÷ 2 = 13,407,245.5
If the quotient is a whole number, then 2 and 13,407,245.5 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 | 26,814,491 | |
| -1 | -26,814,491 |
Now, we try dividing 26,814,491 by 3:
26,814,491 ÷ 3 = 8,938,163.6667
If the quotient is a whole number, then 3 and 8,938,163.6667 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 | 26,814,491 | |
| -1 | -26,814,491 |
Let's try dividing by 4:
26,814,491 ÷ 4 = 6,703,622.75
If the quotient is a whole number, then 4 and 6,703,622.75 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 | 26,814,491 | |
| -1 | 26,814,491 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 3,553 | 7,547 | 83,017 | 128,299 | 143,393 | 1,411,289 | 1,577,323 | 2,437,681 | 26,814,491 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -3,553 | -7,547 | -83,017 | -128,299 | -143,393 | -1,411,289 | -1,577,323 | -2,437,681 | -26,814,491 |
