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 635,163,529, 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 | 635,163,529 | |
| -1 | -635,163,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 635,163,529.
Example:
1 x 635,163,529 = 635,163,529
and
-1 x -635,163,529 = 635,163,529
Notice both answers equal 635,163,529
With that explanation out of the way, let's continue. Next, we take the number 635,163,529 and divide it by 2:
635,163,529 ÷ 2 = 317,581,764.5
If the quotient is a whole number, then 2 and 317,581,764.5 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 | 635,163,529 | |
| -1 | -635,163,529 |
Now, we try dividing 635,163,529 by 3:
635,163,529 ÷ 3 = 211,721,176.3333
If the quotient is a whole number, then 3 and 211,721,176.3333 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 | 635,163,529 | |
| -1 | -635,163,529 |
Let's try dividing by 4:
635,163,529 ÷ 4 = 158,790,882.25
If the quotient is a whole number, then 4 and 158,790,882.25 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 | 635,163,529 | |
| -1 | 635,163,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 1,001 | 7,007 | 90,647 | 634,529 | 997,117 | 1,178,411 | 4,441,703 | 6,979,819 | 8,248,877 | 12,962,521 | 48,858,733 | 57,742,139 | 90,737,647 | 635,163,529 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -1,001 | -7,007 | -90,647 | -634,529 | -997,117 | -1,178,411 | -4,441,703 | -6,979,819 | -8,248,877 | -12,962,521 | -48,858,733 | -57,742,139 | -90,737,647 | -635,163,529 |
