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 617,266,045, 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 | 617,266,045 | |
| -1 | -617,266,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 617,266,045.
Example:
1 x 617,266,045 = 617,266,045
and
-1 x -617,266,045 = 617,266,045
Notice both answers equal 617,266,045
With that explanation out of the way, let's continue. Next, we take the number 617,266,045 and divide it by 2:
617,266,045 ÷ 2 = 308,633,022.5
If the quotient is a whole number, then 2 and 308,633,022.5 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 | 617,266,045 | |
| -1 | -617,266,045 |
Now, we try dividing 617,266,045 by 3:
617,266,045 ÷ 3 = 205,755,348.3333
If the quotient is a whole number, then 3 and 205,755,348.3333 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 | 617,266,045 | |
| -1 | -617,266,045 |
Let's try dividing by 4:
617,266,045 ÷ 4 = 154,316,511.25
If the quotient is a whole number, then 4 and 154,316,511.25 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 | 617,266,045 | |
| -1 | 617,266,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 101 | 505 | 1,111 | 5,555 | 111,119 | 555,595 | 1,222,309 | 6,111,545 | 11,223,019 | 56,115,095 | 123,453,209 | 617,266,045 |
| -1 | -5 | -11 | -55 | -101 | -505 | -1,111 | -5,555 | -111,119 | -555,595 | -1,222,309 | -6,111,545 | -11,223,019 | -56,115,095 | -123,453,209 | -617,266,045 |
