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 786,775,801, 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 | 786,775,801 | |
| -1 | -786,775,801 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 786,775,801.
Example:
1 x 786,775,801 = 786,775,801
and
-1 x -786,775,801 = 786,775,801
Notice both answers equal 786,775,801
With that explanation out of the way, let's continue. Next, we take the number 786,775,801 and divide it by 2:
786,775,801 ÷ 2 = 393,387,900.5
If the quotient is a whole number, then 2 and 393,387,900.5 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 | 786,775,801 | |
| -1 | -786,775,801 |
Now, we try dividing 786,775,801 by 3:
786,775,801 ÷ 3 = 262,258,600.3333
If the quotient is a whole number, then 3 and 262,258,600.3333 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 | 786,775,801 | |
| -1 | -786,775,801 |
Let's try dividing by 4:
786,775,801 ÷ 4 = 196,693,950.25
If the quotient is a whole number, then 4 and 196,693,950.25 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 | 786,775,801 | |
| -1 | 786,775,801 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 173 | 343 | 1,211 | 8,477 | 13,259 | 59,339 | 92,813 | 649,691 | 2,293,807 | 4,547,837 | 16,056,649 | 112,396,543 | 786,775,801 |
| -1 | -7 | -49 | -173 | -343 | -1,211 | -8,477 | -13,259 | -59,339 | -92,813 | -649,691 | -2,293,807 | -4,547,837 | -16,056,649 | -112,396,543 | -786,775,801 |
