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 26,663,777, 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 | 26,663,777 | |
| -1 | -26,663,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,663,777.
Example:
1 x 26,663,777 = 26,663,777
and
-1 x -26,663,777 = 26,663,777
Notice both answers equal 26,663,777
With that explanation out of the way, let's continue. Next, we take the number 26,663,777 and divide it by 2:
26,663,777 ÷ 2 = 13,331,888.5
If the quotient is a whole number, then 2 and 13,331,888.5 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 | 26,663,777 | |
| -1 | -26,663,777 |
Now, we try dividing 26,663,777 by 3:
26,663,777 ÷ 3 = 8,887,925.6667
If the quotient is a whole number, then 3 and 8,887,925.6667 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 | 26,663,777 | |
| -1 | -26,663,777 |
Let's try dividing by 4:
26,663,777 ÷ 4 = 6,665,944.25
If the quotient is a whole number, then 4 and 6,665,944.25 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 | 26,663,777 | |
| -1 | 26,663,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 89 | 127 | 337 | 623 | 889 | 2,359 | 11,303 | 29,993 | 42,799 | 79,121 | 209,951 | 299,593 | 3,809,111 | 26,663,777 |
| -1 | -7 | -89 | -127 | -337 | -623 | -889 | -2,359 | -11,303 | -29,993 | -42,799 | -79,121 | -209,951 | -299,593 | -3,809,111 | -26,663,777 |
