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 800,133,635, 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 | 800,133,635 | |
| -1 | -800,133,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 800,133,635.
Example:
1 x 800,133,635 = 800,133,635
and
-1 x -800,133,635 = 800,133,635
Notice both answers equal 800,133,635
With that explanation out of the way, let's continue. Next, we take the number 800,133,635 and divide it by 2:
800,133,635 ÷ 2 = 400,066,817.5
If the quotient is a whole number, then 2 and 400,066,817.5 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 | 800,133,635 | |
| -1 | -800,133,635 |
Now, we try dividing 800,133,635 by 3:
800,133,635 ÷ 3 = 266,711,211.6667
If the quotient is a whole number, then 3 and 266,711,211.6667 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 | 800,133,635 | |
| -1 | -800,133,635 |
Let's try dividing by 4:
800,133,635 ÷ 4 = 200,033,408.75
If the quotient is a whole number, then 4 and 200,033,408.75 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 | 800,133,635 | |
| -1 | 800,133,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 788,309 | 3,941,545 | 5,518,163 | 22,860,961 | 27,590,815 | 114,304,805 | 160,026,727 | 800,133,635 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -788,309 | -3,941,545 | -5,518,163 | -22,860,961 | -27,590,815 | -114,304,805 | -160,026,727 | -800,133,635 |
