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 25,222,225, 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 | 25,222,225 | |
| -1 | -25,222,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,222,225.
Example:
1 x 25,222,225 = 25,222,225
and
-1 x -25,222,225 = 25,222,225
Notice both answers equal 25,222,225
With that explanation out of the way, let's continue. Next, we take the number 25,222,225 and divide it by 2:
25,222,225 ÷ 2 = 12,611,112.5
If the quotient is a whole number, then 2 and 12,611,112.5 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 | 25,222,225 | |
| -1 | -25,222,225 |
Now, we try dividing 25,222,225 by 3:
25,222,225 ÷ 3 = 8,407,408.3333
If the quotient is a whole number, then 3 and 8,407,408.3333 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 | 25,222,225 | |
| -1 | -25,222,225 |
Let's try dividing by 4:
25,222,225 ÷ 4 = 6,305,556.25
If the quotient is a whole number, then 4 and 6,305,556.25 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 | 25,222,225 | |
| -1 | 25,222,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 101 | 175 | 505 | 707 | 1,427 | 2,525 | 3,535 | 7,135 | 9,989 | 17,675 | 35,675 | 49,945 | 144,127 | 249,725 | 720,635 | 1,008,889 | 3,603,175 | 5,044,445 | 25,222,225 |
| -1 | -5 | -7 | -25 | -35 | -101 | -175 | -505 | -707 | -1,427 | -2,525 | -3,535 | -7,135 | -9,989 | -17,675 | -35,675 | -49,945 | -144,127 | -249,725 | -720,635 | -1,008,889 | -3,603,175 | -5,044,445 | -25,222,225 |
