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 26,868,347, 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 | 26,868,347 | |
| -1 | -26,868,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,868,347.
Example:
1 x 26,868,347 = 26,868,347
and
-1 x -26,868,347 = 26,868,347
Notice both answers equal 26,868,347
With that explanation out of the way, let's continue. Next, we take the number 26,868,347 and divide it by 2:
26,868,347 ÷ 2 = 13,434,173.5
If the quotient is a whole number, then 2 and 13,434,173.5 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 | 26,868,347 | |
| -1 | -26,868,347 |
Now, we try dividing 26,868,347 by 3:
26,868,347 ÷ 3 = 8,956,115.6667
If the quotient is a whole number, then 3 and 8,956,115.6667 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 | 26,868,347 | |
| -1 | -26,868,347 |
Let's try dividing by 4:
26,868,347 ÷ 4 = 6,717,086.75
If the quotient is a whole number, then 4 and 6,717,086.75 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 | 26,868,347 | |
| -1 | 26,868,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 23 | 187 | 253 | 391 | 4,301 | 6,247 | 68,717 | 106,199 | 143,681 | 1,168,189 | 1,580,491 | 2,442,577 | 26,868,347 |
| -1 | -11 | -17 | -23 | -187 | -253 | -391 | -4,301 | -6,247 | -68,717 | -106,199 | -143,681 | -1,168,189 | -1,580,491 | -2,442,577 | -26,868,347 |
