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 530,705,617, 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 | 530,705,617 | |
| -1 | -530,705,617 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,705,617.
Example:
1 x 530,705,617 = 530,705,617
and
-1 x -530,705,617 = 530,705,617
Notice both answers equal 530,705,617
With that explanation out of the way, let's continue. Next, we take the number 530,705,617 and divide it by 2:
530,705,617 ÷ 2 = 265,352,808.5
If the quotient is a whole number, then 2 and 265,352,808.5 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 | 530,705,617 | |
| -1 | -530,705,617 |
Now, we try dividing 530,705,617 by 3:
530,705,617 ÷ 3 = 176,901,872.3333
If the quotient is a whole number, then 3 and 176,901,872.3333 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 | 530,705,617 | |
| -1 | -530,705,617 |
Let's try dividing by 4:
530,705,617 ÷ 4 = 132,676,404.25
If the quotient is a whole number, then 4 and 132,676,404.25 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 | 530,705,617 | |
| -1 | 530,705,617 |
If you did it right, you will end up with this table:
| 1 | 13 | 71 | 347 | 923 | 1,657 | 4,511 | 21,541 | 24,637 | 117,647 | 320,281 | 574,979 | 1,529,411 | 7,474,727 | 40,823,509 | 530,705,617 |
| -1 | -13 | -71 | -347 | -923 | -1,657 | -4,511 | -21,541 | -24,637 | -117,647 | -320,281 | -574,979 | -1,529,411 | -7,474,727 | -40,823,509 | -530,705,617 |
