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 622,546,505, 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 | 622,546,505 | |
| -1 | -622,546,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 622,546,505.
Example:
1 x 622,546,505 = 622,546,505
and
-1 x -622,546,505 = 622,546,505
Notice both answers equal 622,546,505
With that explanation out of the way, let's continue. Next, we take the number 622,546,505 and divide it by 2:
622,546,505 ÷ 2 = 311,273,252.5
If the quotient is a whole number, then 2 and 311,273,252.5 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 | 622,546,505 | |
| -1 | -622,546,505 |
Now, we try dividing 622,546,505 by 3:
622,546,505 ÷ 3 = 207,515,501.6667
If the quotient is a whole number, then 3 and 207,515,501.6667 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 | 622,546,505 | |
| -1 | -622,546,505 |
Let's try dividing by 4:
622,546,505 ÷ 4 = 155,636,626.25
If the quotient is a whole number, then 4 and 155,636,626.25 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 | 622,546,505 | |
| -1 | 622,546,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,791 | 6,373 | 13,955 | 19,537 | 31,865 | 44,611 | 97,685 | 223,055 | 17,787,043 | 88,935,215 | 124,509,301 | 622,546,505 |
| -1 | -5 | -7 | -35 | -2,791 | -6,373 | -13,955 | -19,537 | -31,865 | -44,611 | -97,685 | -223,055 | -17,787,043 | -88,935,215 | -124,509,301 | -622,546,505 |
