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 7,086,425, 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 | 7,086,425 | |
| -1 | -7,086,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,086,425.
Example:
1 x 7,086,425 = 7,086,425
and
-1 x -7,086,425 = 7,086,425
Notice both answers equal 7,086,425
With that explanation out of the way, let's continue. Next, we take the number 7,086,425 and divide it by 2:
7,086,425 ÷ 2 = 3,543,212.5
If the quotient is a whole number, then 2 and 3,543,212.5 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 | 7,086,425 | |
| -1 | -7,086,425 |
Now, we try dividing 7,086,425 by 3:
7,086,425 ÷ 3 = 2,362,141.6667
If the quotient is a whole number, then 3 and 2,362,141.6667 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 | 7,086,425 | |
| -1 | -7,086,425 |
Let's try dividing by 4:
7,086,425 ÷ 4 = 1,771,606.25
If the quotient is a whole number, then 4 and 1,771,606.25 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 | 7,086,425 | |
| -1 | 7,086,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 47 | 163 | 185 | 235 | 815 | 925 | 1,175 | 1,739 | 4,075 | 6,031 | 7,661 | 8,695 | 30,155 | 38,305 | 43,475 | 150,775 | 191,525 | 283,457 | 1,417,285 | 7,086,425 |
| -1 | -5 | -25 | -37 | -47 | -163 | -185 | -235 | -815 | -925 | -1,175 | -1,739 | -4,075 | -6,031 | -7,661 | -8,695 | -30,155 | -38,305 | -43,475 | -150,775 | -191,525 | -283,457 | -1,417,285 | -7,086,425 |
