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 26,217,775, 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 | 26,217,775 | |
| -1 | -26,217,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,217,775.
Example:
1 x 26,217,775 = 26,217,775
and
-1 x -26,217,775 = 26,217,775
Notice both answers equal 26,217,775
With that explanation out of the way, let's continue. Next, we take the number 26,217,775 and divide it by 2:
26,217,775 ÷ 2 = 13,108,887.5
If the quotient is a whole number, then 2 and 13,108,887.5 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 | 26,217,775 | |
| -1 | -26,217,775 |
Now, we try dividing 26,217,775 by 3:
26,217,775 ÷ 3 = 8,739,258.3333
If the quotient is a whole number, then 3 and 8,739,258.3333 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 | 26,217,775 | |
| -1 | -26,217,775 |
Let's try dividing by 4:
26,217,775 ÷ 4 = 6,554,443.75
If the quotient is a whole number, then 4 and 6,554,443.75 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 | 26,217,775 | |
| -1 | 26,217,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 53 | 235 | 265 | 421 | 1,175 | 1,325 | 2,105 | 2,491 | 10,525 | 12,455 | 19,787 | 22,313 | 62,275 | 98,935 | 111,565 | 494,675 | 557,825 | 1,048,711 | 5,243,555 | 26,217,775 |
| -1 | -5 | -25 | -47 | -53 | -235 | -265 | -421 | -1,175 | -1,325 | -2,105 | -2,491 | -10,525 | -12,455 | -19,787 | -22,313 | -62,275 | -98,935 | -111,565 | -494,675 | -557,825 | -1,048,711 | -5,243,555 | -26,217,775 |
