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 560,785,421, 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 | 560,785,421 | |
| -1 | -560,785,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 560,785,421.
Example:
1 x 560,785,421 = 560,785,421
and
-1 x -560,785,421 = 560,785,421
Notice both answers equal 560,785,421
With that explanation out of the way, let's continue. Next, we take the number 560,785,421 and divide it by 2:
560,785,421 ÷ 2 = 280,392,710.5
If the quotient is a whole number, then 2 and 280,392,710.5 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 | 560,785,421 | |
| -1 | -560,785,421 |
Now, we try dividing 560,785,421 by 3:
560,785,421 ÷ 3 = 186,928,473.6667
If the quotient is a whole number, then 3 and 186,928,473.6667 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 | 560,785,421 | |
| -1 | -560,785,421 |
Let's try dividing by 4:
560,785,421 ÷ 4 = 140,196,355.25
If the quotient is a whole number, then 4 and 140,196,355.25 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 | 560,785,421 | |
| -1 | 560,785,421 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 97 | 371 | 679 | 5,141 | 15,583 | 35,987 | 109,081 | 825,899 | 1,511,551 | 5,781,293 | 10,580,857 | 80,112,203 | 560,785,421 |
| -1 | -7 | -53 | -97 | -371 | -679 | -5,141 | -15,583 | -35,987 | -109,081 | -825,899 | -1,511,551 | -5,781,293 | -10,580,857 | -80,112,203 | -560,785,421 |
