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 7,112,567, 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 | 7,112,567 | |
| -1 | -7,112,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,112,567.
Example:
1 x 7,112,567 = 7,112,567
and
-1 x -7,112,567 = 7,112,567
Notice both answers equal 7,112,567
With that explanation out of the way, let's continue. Next, we take the number 7,112,567 and divide it by 2:
7,112,567 ÷ 2 = 3,556,283.5
If the quotient is a whole number, then 2 and 3,556,283.5 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 | 7,112,567 | |
| -1 | -7,112,567 |
Now, we try dividing 7,112,567 by 3:
7,112,567 ÷ 3 = 2,370,855.6667
If the quotient is a whole number, then 3 and 2,370,855.6667 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 | 7,112,567 | |
| -1 | -7,112,567 |
Let's try dividing by 4:
7,112,567 ÷ 4 = 1,778,141.75
If the quotient is a whole number, then 4 and 1,778,141.75 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 | 7,112,567 | |
| -1 | 7,112,567 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 71 | 77 | 497 | 781 | 1,301 | 5,467 | 9,107 | 14,311 | 92,371 | 100,177 | 646,597 | 1,016,081 | 7,112,567 |
| -1 | -7 | -11 | -71 | -77 | -497 | -781 | -1,301 | -5,467 | -9,107 | -14,311 | -92,371 | -100,177 | -646,597 | -1,016,081 | -7,112,567 |
