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 26,542,115, 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 | 26,542,115 | |
| -1 | -26,542,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,542,115.
Example:
1 x 26,542,115 = 26,542,115
and
-1 x -26,542,115 = 26,542,115
Notice both answers equal 26,542,115
With that explanation out of the way, let's continue. Next, we take the number 26,542,115 and divide it by 2:
26,542,115 ÷ 2 = 13,271,057.5
If the quotient is a whole number, then 2 and 13,271,057.5 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 | 26,542,115 | |
| -1 | -26,542,115 |
Now, we try dividing 26,542,115 by 3:
26,542,115 ÷ 3 = 8,847,371.6667
If the quotient is a whole number, then 3 and 8,847,371.6667 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 | 26,542,115 | |
| -1 | -26,542,115 |
Let's try dividing by 4:
26,542,115 ÷ 4 = 6,635,528.75
If the quotient is a whole number, then 4 and 6,635,528.75 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 | 26,542,115 | |
| -1 | 26,542,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 149 | 745 | 1,549 | 3,427 | 7,745 | 17,135 | 35,627 | 178,135 | 230,801 | 1,154,005 | 5,308,423 | 26,542,115 |
| -1 | -5 | -23 | -115 | -149 | -745 | -1,549 | -3,427 | -7,745 | -17,135 | -35,627 | -178,135 | -230,801 | -1,154,005 | -5,308,423 | -26,542,115 |
