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 562,120,055, 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 | 562,120,055 | |
| -1 | -562,120,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 562,120,055.
Example:
1 x 562,120,055 = 562,120,055
and
-1 x -562,120,055 = 562,120,055
Notice both answers equal 562,120,055
With that explanation out of the way, let's continue. Next, we take the number 562,120,055 and divide it by 2:
562,120,055 ÷ 2 = 281,060,027.5
If the quotient is a whole number, then 2 and 281,060,027.5 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 | 562,120,055 | |
| -1 | -562,120,055 |
Now, we try dividing 562,120,055 by 3:
562,120,055 ÷ 3 = 187,373,351.6667
If the quotient is a whole number, then 3 and 187,373,351.6667 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 | 562,120,055 | |
| -1 | -562,120,055 |
Let's try dividing by 4:
562,120,055 ÷ 4 = 140,530,013.75
If the quotient is a whole number, then 4 and 140,530,013.75 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 | 562,120,055 | |
| -1 | 562,120,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 518,083 | 2,590,415 | 3,626,581 | 16,060,573 | 18,132,905 | 80,302,865 | 112,424,011 | 562,120,055 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -518,083 | -2,590,415 | -3,626,581 | -16,060,573 | -18,132,905 | -80,302,865 | -112,424,011 | -562,120,055 |
