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 26,111,225, 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 | 26,111,225 | |
| -1 | -26,111,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,111,225.
Example:
1 x 26,111,225 = 26,111,225
and
-1 x -26,111,225 = 26,111,225
Notice both answers equal 26,111,225
With that explanation out of the way, let's continue. Next, we take the number 26,111,225 and divide it by 2:
26,111,225 ÷ 2 = 13,055,612.5
If the quotient is a whole number, then 2 and 13,055,612.5 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 | 26,111,225 | |
| -1 | -26,111,225 |
Now, we try dividing 26,111,225 by 3:
26,111,225 ÷ 3 = 8,703,741.6667
If the quotient is a whole number, then 3 and 8,703,741.6667 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 | 26,111,225 | |
| -1 | -26,111,225 |
Let's try dividing by 4:
26,111,225 ÷ 4 = 6,527,806.25
If the quotient is a whole number, then 4 and 6,527,806.25 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 | 26,111,225 | |
| -1 | 26,111,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 25 | 35 | 95 | 133 | 175 | 475 | 665 | 3,325 | 7,853 | 39,265 | 54,971 | 149,207 | 196,325 | 274,855 | 746,035 | 1,044,449 | 1,374,275 | 3,730,175 | 5,222,245 | 26,111,225 |
| -1 | -5 | -7 | -19 | -25 | -35 | -95 | -133 | -175 | -475 | -665 | -3,325 | -7,853 | -39,265 | -54,971 | -149,207 | -196,325 | -274,855 | -746,035 | -1,044,449 | -1,374,275 | -3,730,175 | -5,222,245 | -26,111,225 |
