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 7,062,385, 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 | 7,062,385 | |
| -1 | -7,062,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,062,385.
Example:
1 x 7,062,385 = 7,062,385
and
-1 x -7,062,385 = 7,062,385
Notice both answers equal 7,062,385
With that explanation out of the way, let's continue. Next, we take the number 7,062,385 and divide it by 2:
7,062,385 ÷ 2 = 3,531,192.5
If the quotient is a whole number, then 2 and 3,531,192.5 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 | 7,062,385 | |
| -1 | -7,062,385 |
Now, we try dividing 7,062,385 by 3:
7,062,385 ÷ 3 = 2,354,128.3333
If the quotient is a whole number, then 3 and 2,354,128.3333 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 | 7,062,385 | |
| -1 | -7,062,385 |
Let's try dividing by 4:
7,062,385 ÷ 4 = 1,765,596.25
If the quotient is a whole number, then 4 and 1,765,596.25 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 | 7,062,385 | |
| -1 | 7,062,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 73 | 365 | 803 | 1,759 | 4,015 | 8,795 | 19,349 | 96,745 | 128,407 | 642,035 | 1,412,477 | 7,062,385 |
| -1 | -5 | -11 | -55 | -73 | -365 | -803 | -1,759 | -4,015 | -8,795 | -19,349 | -96,745 | -128,407 | -642,035 | -1,412,477 | -7,062,385 |
