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 26,315,035, 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 | 26,315,035 | |
| -1 | -26,315,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,315,035.
Example:
1 x 26,315,035 = 26,315,035
and
-1 x -26,315,035 = 26,315,035
Notice both answers equal 26,315,035
With that explanation out of the way, let's continue. Next, we take the number 26,315,035 and divide it by 2:
26,315,035 ÷ 2 = 13,157,517.5
If the quotient is a whole number, then 2 and 13,157,517.5 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 | 26,315,035 | |
| -1 | -26,315,035 |
Now, we try dividing 26,315,035 by 3:
26,315,035 ÷ 3 = 8,771,678.3333
If the quotient is a whole number, then 3 and 8,771,678.3333 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 | 26,315,035 | |
| -1 | -26,315,035 |
Let's try dividing by 4:
26,315,035 ÷ 4 = 6,578,758.75
If the quotient is a whole number, then 4 and 6,578,758.75 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 | 26,315,035 | |
| -1 | 26,315,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 127 | 145 | 635 | 1,429 | 3,683 | 7,145 | 18,415 | 41,441 | 181,483 | 207,205 | 907,415 | 5,263,007 | 26,315,035 |
| -1 | -5 | -29 | -127 | -145 | -635 | -1,429 | -3,683 | -7,145 | -18,415 | -41,441 | -181,483 | -207,205 | -907,415 | -5,263,007 | -26,315,035 |
