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 7,070,665, 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 | 7,070,665 | |
| -1 | -7,070,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,070,665.
Example:
1 x 7,070,665 = 7,070,665
and
-1 x -7,070,665 = 7,070,665
Notice both answers equal 7,070,665
With that explanation out of the way, let's continue. Next, we take the number 7,070,665 and divide it by 2:
7,070,665 ÷ 2 = 3,535,332.5
If the quotient is a whole number, then 2 and 3,535,332.5 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 | 7,070,665 | |
| -1 | -7,070,665 |
Now, we try dividing 7,070,665 by 3:
7,070,665 ÷ 3 = 2,356,888.3333
If the quotient is a whole number, then 3 and 2,356,888.3333 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 | 7,070,665 | |
| -1 | -7,070,665 |
Let's try dividing by 4:
7,070,665 ÷ 4 = 1,767,666.25
If the quotient is a whole number, then 4 and 1,767,666.25 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 | 7,070,665 | |
| -1 | 7,070,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 269 | 751 | 1,345 | 1,883 | 3,755 | 5,257 | 9,415 | 26,285 | 202,019 | 1,010,095 | 1,414,133 | 7,070,665 |
| -1 | -5 | -7 | -35 | -269 | -751 | -1,345 | -1,883 | -3,755 | -5,257 | -9,415 | -26,285 | -202,019 | -1,010,095 | -1,414,133 | -7,070,665 |
