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 67,127,555, 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 | 67,127,555 | |
| -1 | -67,127,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 67,127,555.
Example:
1 x 67,127,555 = 67,127,555
and
-1 x -67,127,555 = 67,127,555
Notice both answers equal 67,127,555
With that explanation out of the way, let's continue. Next, we take the number 67,127,555 and divide it by 2:
67,127,555 ÷ 2 = 33,563,777.5
If the quotient is a whole number, then 2 and 33,563,777.5 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 | 67,127,555 | |
| -1 | -67,127,555 |
Now, we try dividing 67,127,555 by 3:
67,127,555 ÷ 3 = 22,375,851.6667
If the quotient is a whole number, then 3 and 22,375,851.6667 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 | 67,127,555 | |
| -1 | -67,127,555 |
Let's try dividing by 4:
67,127,555 ÷ 4 = 16,781,888.75
If the quotient is a whole number, then 4 and 16,781,888.75 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 | 67,127,555 | |
| -1 | 67,127,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 39,371 | 196,855 | 433,081 | 1,220,501 | 2,165,405 | 6,102,505 | 13,425,511 | 67,127,555 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -39,371 | -196,855 | -433,081 | -1,220,501 | -2,165,405 | -6,102,505 | -13,425,511 | -67,127,555 |
