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 775,516,345, 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 | 775,516,345 | |
| -1 | -775,516,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 775,516,345.
Example:
1 x 775,516,345 = 775,516,345
and
-1 x -775,516,345 = 775,516,345
Notice both answers equal 775,516,345
With that explanation out of the way, let's continue. Next, we take the number 775,516,345 and divide it by 2:
775,516,345 ÷ 2 = 387,758,172.5
If the quotient is a whole number, then 2 and 387,758,172.5 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 | 775,516,345 | |
| -1 | -775,516,345 |
Now, we try dividing 775,516,345 by 3:
775,516,345 ÷ 3 = 258,505,448.3333
If the quotient is a whole number, then 3 and 258,505,448.3333 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 | 775,516,345 | |
| -1 | -775,516,345 |
Let's try dividing by 4:
775,516,345 ÷ 4 = 193,879,086.25
If the quotient is a whole number, then 4 and 193,879,086.25 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 | 775,516,345 | |
| -1 | 775,516,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 191 | 727 | 955 | 1,117 | 3,635 | 5,585 | 138,857 | 213,347 | 694,285 | 812,059 | 1,066,735 | 4,060,295 | 155,103,269 | 775,516,345 |
| -1 | -5 | -191 | -727 | -955 | -1,117 | -3,635 | -5,585 | -138,857 | -213,347 | -694,285 | -812,059 | -1,066,735 | -4,060,295 | -155,103,269 | -775,516,345 |
