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 13,450,325, 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 | 13,450,325 | |
| -1 | -13,450,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,450,325.
Example:
1 x 13,450,325 = 13,450,325
and
-1 x -13,450,325 = 13,450,325
Notice both answers equal 13,450,325
With that explanation out of the way, let's continue. Next, we take the number 13,450,325 and divide it by 2:
13,450,325 ÷ 2 = 6,725,162.5
If the quotient is a whole number, then 2 and 6,725,162.5 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 | 13,450,325 | |
| -1 | -13,450,325 |
Now, we try dividing 13,450,325 by 3:
13,450,325 ÷ 3 = 4,483,441.6667
If the quotient is a whole number, then 3 and 4,483,441.6667 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 | 13,450,325 | |
| -1 | -13,450,325 |
Let's try dividing by 4:
13,450,325 ÷ 4 = 3,362,581.25
If the quotient is a whole number, then 4 and 3,362,581.25 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 | 13,450,325 | |
| -1 | 13,450,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 151 | 175 | 509 | 755 | 1,057 | 2,545 | 3,563 | 3,775 | 5,285 | 12,725 | 17,815 | 26,425 | 76,859 | 89,075 | 384,295 | 538,013 | 1,921,475 | 2,690,065 | 13,450,325 |
| -1 | -5 | -7 | -25 | -35 | -151 | -175 | -509 | -755 | -1,057 | -2,545 | -3,563 | -3,775 | -5,285 | -12,725 | -17,815 | -26,425 | -76,859 | -89,075 | -384,295 | -538,013 | -1,921,475 | -2,690,065 | -13,450,325 |
