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 833,073,625, 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 | 833,073,625 | |
| -1 | -833,073,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 833,073,625.
Example:
1 x 833,073,625 = 833,073,625
and
-1 x -833,073,625 = 833,073,625
Notice both answers equal 833,073,625
With that explanation out of the way, let's continue. Next, we take the number 833,073,625 and divide it by 2:
833,073,625 ÷ 2 = 416,536,812.5
If the quotient is a whole number, then 2 and 416,536,812.5 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 | 833,073,625 | |
| -1 | -833,073,625 |
Now, we try dividing 833,073,625 by 3:
833,073,625 ÷ 3 = 277,691,208.3333
If the quotient is a whole number, then 3 and 277,691,208.3333 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 | 833,073,625 | |
| -1 | -833,073,625 |
Let's try dividing by 4:
833,073,625 ÷ 4 = 208,268,406.25
If the quotient is a whole number, then 4 and 208,268,406.25 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 | 833,073,625 | |
| -1 | 833,073,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 523 | 2,615 | 12,743 | 13,075 | 63,715 | 65,375 | 318,575 | 1,592,875 | 6,664,589 | 33,322,945 | 166,614,725 | 833,073,625 |
| -1 | -5 | -25 | -125 | -523 | -2,615 | -12,743 | -13,075 | -63,715 | -65,375 | -318,575 | -1,592,875 | -6,664,589 | -33,322,945 | -166,614,725 | -833,073,625 |
