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 26,014,495, 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 | 26,014,495 | |
| -1 | -26,014,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,014,495.
Example:
1 x 26,014,495 = 26,014,495
and
-1 x -26,014,495 = 26,014,495
Notice both answers equal 26,014,495
With that explanation out of the way, let's continue. Next, we take the number 26,014,495 and divide it by 2:
26,014,495 ÷ 2 = 13,007,247.5
If the quotient is a whole number, then 2 and 13,007,247.5 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 | 26,014,495 | |
| -1 | -26,014,495 |
Now, we try dividing 26,014,495 by 3:
26,014,495 ÷ 3 = 8,671,498.3333
If the quotient is a whole number, then 3 and 8,671,498.3333 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 | 26,014,495 | |
| -1 | -26,014,495 |
Let's try dividing by 4:
26,014,495 ÷ 4 = 6,503,623.75
If the quotient is a whole number, then 4 and 6,503,623.75 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 | 26,014,495 | |
| -1 | 26,014,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 17,401 | 87,005 | 226,213 | 400,223 | 1,131,065 | 2,001,115 | 5,202,899 | 26,014,495 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -17,401 | -87,005 | -226,213 | -400,223 | -1,131,065 | -2,001,115 | -5,202,899 | -26,014,495 |
