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 78,162,695, 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 | 78,162,695 | |
| -1 | -78,162,695 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 78,162,695.
Example:
1 x 78,162,695 = 78,162,695
and
-1 x -78,162,695 = 78,162,695
Notice both answers equal 78,162,695
With that explanation out of the way, let's continue. Next, we take the number 78,162,695 and divide it by 2:
78,162,695 ÷ 2 = 39,081,347.5
If the quotient is a whole number, then 2 and 39,081,347.5 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 | 78,162,695 | |
| -1 | -78,162,695 |
Now, we try dividing 78,162,695 by 3:
78,162,695 ÷ 3 = 26,054,231.6667
If the quotient is a whole number, then 3 and 26,054,231.6667 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 | 78,162,695 | |
| -1 | -78,162,695 |
Let's try dividing by 4:
78,162,695 ÷ 4 = 19,540,673.75
If the quotient is a whole number, then 4 and 19,540,673.75 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 | 78,162,695 | |
| -1 | 78,162,695 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 257 | 1,285 | 3,341 | 4,679 | 16,705 | 23,395 | 60,827 | 304,135 | 1,202,503 | 6,012,515 | 15,632,539 | 78,162,695 |
| -1 | -5 | -13 | -65 | -257 | -1,285 | -3,341 | -4,679 | -16,705 | -23,395 | -60,827 | -304,135 | -1,202,503 | -6,012,515 | -15,632,539 | -78,162,695 |
