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 67,605,595, 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 | 67,605,595 | |
| -1 | -67,605,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,605,595.
Example:
1 x 67,605,595 = 67,605,595
and
-1 x -67,605,595 = 67,605,595
Notice both answers equal 67,605,595
With that explanation out of the way, let's continue. Next, we take the number 67,605,595 and divide it by 2:
67,605,595 ÷ 2 = 33,802,797.5
If the quotient is a whole number, then 2 and 33,802,797.5 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 | 67,605,595 | |
| -1 | -67,605,595 |
Now, we try dividing 67,605,595 by 3:
67,605,595 ÷ 3 = 22,535,198.3333
If the quotient is a whole number, then 3 and 22,535,198.3333 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 | 67,605,595 | |
| -1 | -67,605,595 |
Let's try dividing by 4:
67,605,595 ÷ 4 = 16,901,398.75
If the quotient is a whole number, then 4 and 16,901,398.75 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 | 67,605,595 | |
| -1 | 67,605,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 103 | 251 | 515 | 523 | 1,255 | 2,615 | 25,853 | 53,869 | 129,265 | 131,273 | 269,345 | 656,365 | 13,521,119 | 67,605,595 |
| -1 | -5 | -103 | -251 | -515 | -523 | -1,255 | -2,615 | -25,853 | -53,869 | -129,265 | -131,273 | -269,345 | -656,365 | -13,521,119 | -67,605,595 |
