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 26,223,785, 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 | 26,223,785 | |
| -1 | -26,223,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,223,785.
Example:
1 x 26,223,785 = 26,223,785
and
-1 x -26,223,785 = 26,223,785
Notice both answers equal 26,223,785
With that explanation out of the way, let's continue. Next, we take the number 26,223,785 and divide it by 2:
26,223,785 ÷ 2 = 13,111,892.5
If the quotient is a whole number, then 2 and 13,111,892.5 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 | 26,223,785 | |
| -1 | -26,223,785 |
Now, we try dividing 26,223,785 by 3:
26,223,785 ÷ 3 = 8,741,261.6667
If the quotient is a whole number, then 3 and 8,741,261.6667 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 | 26,223,785 | |
| -1 | -26,223,785 |
Let's try dividing by 4:
26,223,785 ÷ 4 = 6,555,946.25
If the quotient is a whole number, then 4 and 6,555,946.25 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 | 26,223,785 | |
| -1 | 26,223,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 683 | 1,097 | 3,415 | 4,781 | 5,485 | 7,679 | 23,905 | 38,395 | 749,251 | 3,746,255 | 5,244,757 | 26,223,785 |
| -1 | -5 | -7 | -35 | -683 | -1,097 | -3,415 | -4,781 | -5,485 | -7,679 | -23,905 | -38,395 | -749,251 | -3,746,255 | -5,244,757 | -26,223,785 |
