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 26,417,657, 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 | 26,417,657 | |
| -1 | -26,417,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,417,657.
Example:
1 x 26,417,657 = 26,417,657
and
-1 x -26,417,657 = 26,417,657
Notice both answers equal 26,417,657
With that explanation out of the way, let's continue. Next, we take the number 26,417,657 and divide it by 2:
26,417,657 ÷ 2 = 13,208,828.5
If the quotient is a whole number, then 2 and 13,208,828.5 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 | 26,417,657 | |
| -1 | -26,417,657 |
Now, we try dividing 26,417,657 by 3:
26,417,657 ÷ 3 = 8,805,885.6667
If the quotient is a whole number, then 3 and 8,805,885.6667 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 | 26,417,657 | |
| -1 | -26,417,657 |
Let's try dividing by 4:
26,417,657 ÷ 4 = 6,604,414.25
If the quotient is a whole number, then 4 and 6,604,414.25 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 | 26,417,657 | |
| -1 | 26,417,657 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 307 | 647 | 2,149 | 4,529 | 5,833 | 12,293 | 40,831 | 86,051 | 198,629 | 1,390,403 | 3,773,951 | 26,417,657 |
| -1 | -7 | -19 | -133 | -307 | -647 | -2,149 | -4,529 | -5,833 | -12,293 | -40,831 | -86,051 | -198,629 | -1,390,403 | -3,773,951 | -26,417,657 |
