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 565,403,545, 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 | 565,403,545 | |
| -1 | -565,403,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 565,403,545.
Example:
1 x 565,403,545 = 565,403,545
and
-1 x -565,403,545 = 565,403,545
Notice both answers equal 565,403,545
With that explanation out of the way, let's continue. Next, we take the number 565,403,545 and divide it by 2:
565,403,545 ÷ 2 = 282,701,772.5
If the quotient is a whole number, then 2 and 282,701,772.5 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 | 565,403,545 | |
| -1 | -565,403,545 |
Now, we try dividing 565,403,545 by 3:
565,403,545 ÷ 3 = 188,467,848.3333
If the quotient is a whole number, then 3 and 188,467,848.3333 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 | 565,403,545 | |
| -1 | -565,403,545 |
Let's try dividing by 4:
565,403,545 ÷ 4 = 141,350,886.25
If the quotient is a whole number, then 4 and 141,350,886.25 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 | 565,403,545 | |
| -1 | 565,403,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 3,793 | 4,259 | 18,965 | 21,295 | 26,551 | 29,813 | 132,755 | 149,065 | 16,154,387 | 80,771,935 | 113,080,709 | 565,403,545 |
| -1 | -5 | -7 | -35 | -3,793 | -4,259 | -18,965 | -21,295 | -26,551 | -29,813 | -132,755 | -149,065 | -16,154,387 | -80,771,935 | -113,080,709 | -565,403,545 |
