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 67,259,555, 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 | 67,259,555 | |
| -1 | -67,259,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,259,555.
Example:
1 x 67,259,555 = 67,259,555
and
-1 x -67,259,555 = 67,259,555
Notice both answers equal 67,259,555
With that explanation out of the way, let's continue. Next, we take the number 67,259,555 and divide it by 2:
67,259,555 ÷ 2 = 33,629,777.5
If the quotient is a whole number, then 2 and 33,629,777.5 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 | 67,259,555 | |
| -1 | -67,259,555 |
Now, we try dividing 67,259,555 by 3:
67,259,555 ÷ 3 = 22,419,851.6667
If the quotient is a whole number, then 3 and 22,419,851.6667 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 | 67,259,555 | |
| -1 | -67,259,555 |
Let's try dividing by 4:
67,259,555 ÷ 4 = 16,814,888.75
If the quotient is a whole number, then 4 and 16,814,888.75 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 | 67,259,555 | |
| -1 | 67,259,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 42,169 | 210,845 | 463,859 | 1,222,901 | 2,319,295 | 6,114,505 | 13,451,911 | 67,259,555 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -42,169 | -210,845 | -463,859 | -1,222,901 | -2,319,295 | -6,114,505 | -13,451,911 | -67,259,555 |
