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 533,210,755, 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 | 533,210,755 | |
| -1 | -533,210,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,210,755.
Example:
1 x 533,210,755 = 533,210,755
and
-1 x -533,210,755 = 533,210,755
Notice both answers equal 533,210,755
With that explanation out of the way, let's continue. Next, we take the number 533,210,755 and divide it by 2:
533,210,755 ÷ 2 = 266,605,377.5
If the quotient is a whole number, then 2 and 266,605,377.5 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 | 533,210,755 | |
| -1 | -533,210,755 |
Now, we try dividing 533,210,755 by 3:
533,210,755 ÷ 3 = 177,736,918.3333
If the quotient is a whole number, then 3 and 177,736,918.3333 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 | 533,210,755 | |
| -1 | -533,210,755 |
Let's try dividing by 4:
533,210,755 ÷ 4 = 133,302,688.75
If the quotient is a whole number, then 4 and 133,302,688.75 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 | 533,210,755 | |
| -1 | 533,210,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 1,384,963 | 6,924,815 | 9,694,741 | 15,234,593 | 48,473,705 | 76,172,965 | 106,642,151 | 533,210,755 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -1,384,963 | -6,924,815 | -9,694,741 | -15,234,593 | -48,473,705 | -76,172,965 | -106,642,151 | -533,210,755 |
