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 26,000,195, 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 | 26,000,195 | |
| -1 | -26,000,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,000,195.
Example:
1 x 26,000,195 = 26,000,195
and
-1 x -26,000,195 = 26,000,195
Notice both answers equal 26,000,195
With that explanation out of the way, let's continue. Next, we take the number 26,000,195 and divide it by 2:
26,000,195 ÷ 2 = 13,000,097.5
If the quotient is a whole number, then 2 and 13,000,097.5 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 | 26,000,195 | |
| -1 | -26,000,195 |
Now, we try dividing 26,000,195 by 3:
26,000,195 ÷ 3 = 8,666,731.6667
If the quotient is a whole number, then 3 and 8,666,731.6667 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 | 26,000,195 | |
| -1 | -26,000,195 |
Let's try dividing by 4:
26,000,195 ÷ 4 = 6,500,048.75
If the quotient is a whole number, then 4 and 6,500,048.75 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 | 26,000,195 | |
| -1 | 26,000,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 269 | 1,345 | 1,487 | 3,497 | 7,435 | 17,485 | 19,331 | 96,655 | 400,003 | 2,000,015 | 5,200,039 | 26,000,195 |
| -1 | -5 | -13 | -65 | -269 | -1,345 | -1,487 | -3,497 | -7,435 | -17,485 | -19,331 | -96,655 | -400,003 | -2,000,015 | -5,200,039 | -26,000,195 |
