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 555,771,727, 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 | 555,771,727 | |
| -1 | -555,771,727 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 555,771,727.
Example:
1 x 555,771,727 = 555,771,727
and
-1 x -555,771,727 = 555,771,727
Notice both answers equal 555,771,727
With that explanation out of the way, let's continue. Next, we take the number 555,771,727 and divide it by 2:
555,771,727 ÷ 2 = 277,885,863.5
If the quotient is a whole number, then 2 and 277,885,863.5 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 | 555,771,727 | |
| -1 | -555,771,727 |
Now, we try dividing 555,771,727 by 3:
555,771,727 ÷ 3 = 185,257,242.3333
If the quotient is a whole number, then 3 and 185,257,242.3333 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 | 555,771,727 | |
| -1 | -555,771,727 |
Let's try dividing by 4:
555,771,727 ÷ 4 = 138,942,931.75
If the quotient is a whole number, then 4 and 138,942,931.75 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 | 555,771,727 | |
| -1 | 555,771,727 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 371 | 701 | 2,137 | 4,907 | 14,959 | 37,153 | 113,261 | 260,071 | 792,827 | 1,498,037 | 10,486,259 | 79,395,961 | 555,771,727 |
| -1 | -7 | -53 | -371 | -701 | -2,137 | -4,907 | -14,959 | -37,153 | -113,261 | -260,071 | -792,827 | -1,498,037 | -10,486,259 | -79,395,961 | -555,771,727 |
