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 26,562,217, 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 | 26,562,217 | |
| -1 | -26,562,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,562,217.
Example:
1 x 26,562,217 = 26,562,217
and
-1 x -26,562,217 = 26,562,217
Notice both answers equal 26,562,217
With that explanation out of the way, let's continue. Next, we take the number 26,562,217 and divide it by 2:
26,562,217 ÷ 2 = 13,281,108.5
If the quotient is a whole number, then 2 and 13,281,108.5 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 | 26,562,217 | |
| -1 | -26,562,217 |
Now, we try dividing 26,562,217 by 3:
26,562,217 ÷ 3 = 8,854,072.3333
If the quotient is a whole number, then 3 and 8,854,072.3333 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 | 26,562,217 | |
| -1 | -26,562,217 |
Let's try dividing by 4:
26,562,217 ÷ 4 = 6,640,554.25
If the quotient is a whole number, then 4 and 6,640,554.25 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 | 26,562,217 | |
| -1 | 26,562,217 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 67 | 253 | 737 | 1,541 | 1,567 | 16,951 | 17,237 | 36,041 | 104,989 | 396,451 | 1,154,879 | 2,414,747 | 26,562,217 |
| -1 | -11 | -23 | -67 | -253 | -737 | -1,541 | -1,567 | -16,951 | -17,237 | -36,041 | -104,989 | -396,451 | -1,154,879 | -2,414,747 | -26,562,217 |
