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 533,211,001, 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 | 533,211,001 | |
| -1 | -533,211,001 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 533,211,001.
Example:
1 x 533,211,001 = 533,211,001
and
-1 x -533,211,001 = 533,211,001
Notice both answers equal 533,211,001
With that explanation out of the way, let's continue. Next, we take the number 533,211,001 and divide it by 2:
533,211,001 ÷ 2 = 266,605,500.5
If the quotient is a whole number, then 2 and 266,605,500.5 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 | 533,211,001 | |
| -1 | -533,211,001 |
Now, we try dividing 533,211,001 by 3:
533,211,001 ÷ 3 = 177,737,000.3333
If the quotient is a whole number, then 3 and 177,737,000.3333 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 | 533,211,001 | |
| -1 | -533,211,001 |
Let's try dividing by 4:
533,211,001 ÷ 4 = 133,302,750.25
If the quotient is a whole number, then 4 and 133,302,750.25 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 | 533,211,001 | |
| -1 | 533,211,001 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 391 | 823 | 1,657 | 13,991 | 18,929 | 28,169 | 38,111 | 321,793 | 647,887 | 1,363,711 | 23,183,087 | 31,365,353 | 533,211,001 |
| -1 | -17 | -23 | -391 | -823 | -1,657 | -13,991 | -18,929 | -28,169 | -38,111 | -321,793 | -647,887 | -1,363,711 | -23,183,087 | -31,365,353 | -533,211,001 |
