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 613,032,563, 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 | 613,032,563 | |
| -1 | -613,032,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 613,032,563.
Example:
1 x 613,032,563 = 613,032,563
and
-1 x -613,032,563 = 613,032,563
Notice both answers equal 613,032,563
With that explanation out of the way, let's continue. Next, we take the number 613,032,563 and divide it by 2:
613,032,563 ÷ 2 = 306,516,281.5
If the quotient is a whole number, then 2 and 306,516,281.5 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 | 613,032,563 | |
| -1 | -613,032,563 |
Now, we try dividing 613,032,563 by 3:
613,032,563 ÷ 3 = 204,344,187.6667
If the quotient is a whole number, then 3 and 204,344,187.6667 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 | 613,032,563 | |
| -1 | -613,032,563 |
Let's try dividing by 4:
613,032,563 ÷ 4 = 153,258,140.75
If the quotient is a whole number, then 4 and 153,258,140.75 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 | 613,032,563 | |
| -1 | 613,032,563 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 17 | 143 | 187 | 221 | 2,431 | 252,173 | 2,773,903 | 3,278,249 | 4,286,941 | 36,060,739 | 47,156,351 | 55,730,233 | 613,032,563 |
| -1 | -11 | -13 | -17 | -143 | -187 | -221 | -2,431 | -252,173 | -2,773,903 | -3,278,249 | -4,286,941 | -36,060,739 | -47,156,351 | -55,730,233 | -613,032,563 |
