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 26,389,825, 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 | 26,389,825 | |
| -1 | -26,389,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,389,825.
Example:
1 x 26,389,825 = 26,389,825
and
-1 x -26,389,825 = 26,389,825
Notice both answers equal 26,389,825
With that explanation out of the way, let's continue. Next, we take the number 26,389,825 and divide it by 2:
26,389,825 ÷ 2 = 13,194,912.5
If the quotient is a whole number, then 2 and 13,194,912.5 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 | 26,389,825 | |
| -1 | -26,389,825 |
Now, we try dividing 26,389,825 by 3:
26,389,825 ÷ 3 = 8,796,608.3333
If the quotient is a whole number, then 3 and 8,796,608.3333 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 | 26,389,825 | |
| -1 | -26,389,825 |
Let's try dividing by 4:
26,389,825 ÷ 4 = 6,597,456.25
If the quotient is a whole number, then 4 and 6,597,456.25 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 | 26,389,825 | |
| -1 | 26,389,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 13,709 | 68,545 | 95,963 | 150,799 | 342,725 | 479,815 | 753,995 | 1,055,593 | 2,399,075 | 3,769,975 | 5,277,965 | 26,389,825 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -13,709 | -68,545 | -95,963 | -150,799 | -342,725 | -479,815 | -753,995 | -1,055,593 | -2,399,075 | -3,769,975 | -5,277,965 | -26,389,825 |
