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 564,400,445, 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 | 564,400,445 | |
| -1 | -564,400,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 564,400,445.
Example:
1 x 564,400,445 = 564,400,445
and
-1 x -564,400,445 = 564,400,445
Notice both answers equal 564,400,445
With that explanation out of the way, let's continue. Next, we take the number 564,400,445 and divide it by 2:
564,400,445 ÷ 2 = 282,200,222.5
If the quotient is a whole number, then 2 and 282,200,222.5 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 | 564,400,445 | |
| -1 | -564,400,445 |
Now, we try dividing 564,400,445 by 3:
564,400,445 ÷ 3 = 188,133,481.6667
If the quotient is a whole number, then 3 and 188,133,481.6667 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 | 564,400,445 | |
| -1 | -564,400,445 |
Let's try dividing by 4:
564,400,445 ÷ 4 = 141,100,111.25
If the quotient is a whole number, then 4 and 141,100,111.25 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 | 564,400,445 | |
| -1 | 564,400,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 304,259 | 1,521,295 | 2,129,813 | 10,649,065 | 16,125,727 | 80,628,635 | 112,880,089 | 564,400,445 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -304,259 | -1,521,295 | -2,129,813 | -10,649,065 | -16,125,727 | -80,628,635 | -112,880,089 | -564,400,445 |
