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 824,260,075, 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 | 824,260,075 | |
| -1 | -824,260,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 824,260,075.
Example:
1 x 824,260,075 = 824,260,075
and
-1 x -824,260,075 = 824,260,075
Notice both answers equal 824,260,075
With that explanation out of the way, let's continue. Next, we take the number 824,260,075 and divide it by 2:
824,260,075 ÷ 2 = 412,130,037.5
If the quotient is a whole number, then 2 and 412,130,037.5 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 | 824,260,075 | |
| -1 | -824,260,075 |
Now, we try dividing 824,260,075 by 3:
824,260,075 ÷ 3 = 274,753,358.3333
If the quotient is a whole number, then 3 and 274,753,358.3333 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 | 824,260,075 | |
| -1 | -824,260,075 |
Let's try dividing by 4:
824,260,075 ÷ 4 = 206,065,018.75
If the quotient is a whole number, then 4 and 206,065,018.75 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 | 824,260,075 | |
| -1 | 824,260,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 103 | 515 | 2,575 | 320,101 | 1,600,505 | 8,002,525 | 32,970,403 | 164,852,015 | 824,260,075 |
| -1 | -5 | -25 | -103 | -515 | -2,575 | -320,101 | -1,600,505 | -8,002,525 | -32,970,403 | -164,852,015 | -824,260,075 |
