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 7,011,235, 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 | 7,011,235 | |
| -1 | -7,011,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,011,235.
Example:
1 x 7,011,235 = 7,011,235
and
-1 x -7,011,235 = 7,011,235
Notice both answers equal 7,011,235
With that explanation out of the way, let's continue. Next, we take the number 7,011,235 and divide it by 2:
7,011,235 ÷ 2 = 3,505,617.5
If the quotient is a whole number, then 2 and 3,505,617.5 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 | 7,011,235 | |
| -1 | -7,011,235 |
Now, we try dividing 7,011,235 by 3:
7,011,235 ÷ 3 = 2,337,078.3333
If the quotient is a whole number, then 3 and 2,337,078.3333 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 | 7,011,235 | |
| -1 | -7,011,235 |
Let's try dividing by 4:
7,011,235 ÷ 4 = 1,752,808.75
If the quotient is a whole number, then 4 and 1,752,808.75 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 | 7,011,235 | |
| -1 | 7,011,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 18,211 | 91,055 | 127,477 | 200,321 | 637,385 | 1,001,605 | 1,402,247 | 7,011,235 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -18,211 | -91,055 | -127,477 | -200,321 | -637,385 | -1,001,605 | -1,402,247 | -7,011,235 |
