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 26,634,415, 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 | 26,634,415 | |
| -1 | -26,634,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,634,415.
Example:
1 x 26,634,415 = 26,634,415
and
-1 x -26,634,415 = 26,634,415
Notice both answers equal 26,634,415
With that explanation out of the way, let's continue. Next, we take the number 26,634,415 and divide it by 2:
26,634,415 ÷ 2 = 13,317,207.5
If the quotient is a whole number, then 2 and 13,317,207.5 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 | 26,634,415 | |
| -1 | -26,634,415 |
Now, we try dividing 26,634,415 by 3:
26,634,415 ÷ 3 = 8,878,138.3333
If the quotient is a whole number, then 3 and 8,878,138.3333 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 | 26,634,415 | |
| -1 | -26,634,415 |
Let's try dividing by 4:
26,634,415 ÷ 4 = 6,658,603.75
If the quotient is a whole number, then 4 and 6,658,603.75 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 | 26,634,415 | |
| -1 | 26,634,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 73 | 215 | 365 | 1,697 | 3,139 | 8,485 | 15,695 | 72,971 | 123,881 | 364,855 | 619,405 | 5,326,883 | 26,634,415 |
| -1 | -5 | -43 | -73 | -215 | -365 | -1,697 | -3,139 | -8,485 | -15,695 | -72,971 | -123,881 | -364,855 | -619,405 | -5,326,883 | -26,634,415 |
