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 78,826,969, 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 | 78,826,969 | |
| -1 | -78,826,969 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,826,969.
Example:
1 x 78,826,969 = 78,826,969
and
-1 x -78,826,969 = 78,826,969
Notice both answers equal 78,826,969
With that explanation out of the way, let's continue. Next, we take the number 78,826,969 and divide it by 2:
78,826,969 ÷ 2 = 39,413,484.5
If the quotient is a whole number, then 2 and 39,413,484.5 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 | 78,826,969 | |
| -1 | -78,826,969 |
Now, we try dividing 78,826,969 by 3:
78,826,969 ÷ 3 = 26,275,656.3333
If the quotient is a whole number, then 3 and 26,275,656.3333 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 | 78,826,969 | |
| -1 | -78,826,969 |
Let's try dividing by 4:
78,826,969 ÷ 4 = 19,706,742.25
If the quotient is a whole number, then 4 and 19,706,742.25 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 | 78,826,969 | |
| -1 | 78,826,969 |
If you did it right, you will end up with this table:
| 1 | 13 | 41 | 71 | 533 | 923 | 2,083 | 2,911 | 27,079 | 37,843 | 85,403 | 147,893 | 1,110,239 | 1,922,609 | 6,063,613 | 78,826,969 |
| -1 | -13 | -41 | -71 | -533 | -923 | -2,083 | -2,911 | -27,079 | -37,843 | -85,403 | -147,893 | -1,110,239 | -1,922,609 | -6,063,613 | -78,826,969 |
