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 13,242,425, 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 | 13,242,425 | |
| -1 | -13,242,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,242,425.
Example:
1 x 13,242,425 = 13,242,425
and
-1 x -13,242,425 = 13,242,425
Notice both answers equal 13,242,425
With that explanation out of the way, let's continue. Next, we take the number 13,242,425 and divide it by 2:
13,242,425 ÷ 2 = 6,621,212.5
If the quotient is a whole number, then 2 and 6,621,212.5 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 | 13,242,425 | |
| -1 | -13,242,425 |
Now, we try dividing 13,242,425 by 3:
13,242,425 ÷ 3 = 4,414,141.6667
If the quotient is a whole number, then 3 and 4,414,141.6667 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 | 13,242,425 | |
| -1 | -13,242,425 |
Let's try dividing by 4:
13,242,425 ÷ 4 = 3,310,606.25
If the quotient is a whole number, then 4 and 3,310,606.25 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 | 13,242,425 | |
| -1 | 13,242,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 31 | 35 | 155 | 175 | 217 | 775 | 1,085 | 2,441 | 5,425 | 12,205 | 17,087 | 61,025 | 75,671 | 85,435 | 378,355 | 427,175 | 529,697 | 1,891,775 | 2,648,485 | 13,242,425 |
| -1 | -5 | -7 | -25 | -31 | -35 | -155 | -175 | -217 | -775 | -1,085 | -2,441 | -5,425 | -12,205 | -17,087 | -61,025 | -75,671 | -85,435 | -378,355 | -427,175 | -529,697 | -1,891,775 | -2,648,485 | -13,242,425 |
