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 7,876,967, 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 | 7,876,967 | |
| -1 | -7,876,967 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,876,967.
Example:
1 x 7,876,967 = 7,876,967
and
-1 x -7,876,967 = 7,876,967
Notice both answers equal 7,876,967
With that explanation out of the way, let's continue. Next, we take the number 7,876,967 and divide it by 2:
7,876,967 ÷ 2 = 3,938,483.5
If the quotient is a whole number, then 2 and 3,938,483.5 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 | 7,876,967 | |
| -1 | -7,876,967 |
Now, we try dividing 7,876,967 by 3:
7,876,967 ÷ 3 = 2,625,655.6667
If the quotient is a whole number, then 3 and 2,625,655.6667 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 | 7,876,967 | |
| -1 | -7,876,967 |
Let's try dividing by 4:
7,876,967 ÷ 4 = 1,969,241.75
If the quotient is a whole number, then 4 and 1,969,241.75 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 | 7,876,967 | |
| -1 | 7,876,967 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 119 | 259 | 629 | 1,789 | 4,403 | 12,523 | 30,413 | 66,193 | 212,891 | 463,351 | 1,125,281 | 7,876,967 |
| -1 | -7 | -17 | -37 | -119 | -259 | -629 | -1,789 | -4,403 | -12,523 | -30,413 | -66,193 | -212,891 | -463,351 | -1,125,281 | -7,876,967 |
