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 605,376,107, 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 | 605,376,107 | |
| -1 | -605,376,107 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,376,107.
Example:
1 x 605,376,107 = 605,376,107
and
-1 x -605,376,107 = 605,376,107
Notice both answers equal 605,376,107
With that explanation out of the way, let's continue. Next, we take the number 605,376,107 and divide it by 2:
605,376,107 ÷ 2 = 302,688,053.5
If the quotient is a whole number, then 2 and 302,688,053.5 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 | 605,376,107 | |
| -1 | -605,376,107 |
Now, we try dividing 605,376,107 by 3:
605,376,107 ÷ 3 = 201,792,035.6667
If the quotient is a whole number, then 3 and 201,792,035.6667 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 | 605,376,107 | |
| -1 | -605,376,107 |
Let's try dividing by 4:
605,376,107 ÷ 4 = 151,344,026.75
If the quotient is a whole number, then 4 and 151,344,026.75 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 | 605,376,107 | |
| -1 | 605,376,107 |
If you did it right, you will end up with this table:
| 1 | 7 | 127 | 251 | 889 | 1,757 | 2,713 | 18,991 | 31,877 | 223,139 | 344,551 | 680,963 | 2,411,857 | 4,766,741 | 86,482,301 | 605,376,107 |
| -1 | -7 | -127 | -251 | -889 | -1,757 | -2,713 | -18,991 | -31,877 | -223,139 | -344,551 | -680,963 | -2,411,857 | -4,766,741 | -86,482,301 | -605,376,107 |
