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 273,635,555, 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 | 273,635,555 | |
| -1 | -273,635,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,635,555.
Example:
1 x 273,635,555 = 273,635,555
and
-1 x -273,635,555 = 273,635,555
Notice both answers equal 273,635,555
With that explanation out of the way, let's continue. Next, we take the number 273,635,555 and divide it by 2:
273,635,555 ÷ 2 = 136,817,777.5
If the quotient is a whole number, then 2 and 136,817,777.5 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 | 273,635,555 | |
| -1 | -273,635,555 |
Now, we try dividing 273,635,555 by 3:
273,635,555 ÷ 3 = 91,211,851.6667
If the quotient is a whole number, then 3 and 91,211,851.6667 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 | 273,635,555 | |
| -1 | -273,635,555 |
Let's try dividing by 4:
273,635,555 ÷ 4 = 68,408,888.75
If the quotient is a whole number, then 4 and 68,408,888.75 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 | 273,635,555 | |
| -1 | 273,635,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 265 | 313 | 1,565 | 3,299 | 16,495 | 16,589 | 82,945 | 174,847 | 874,235 | 1,032,587 | 5,162,935 | 54,727,111 | 273,635,555 |
| -1 | -5 | -53 | -265 | -313 | -1,565 | -3,299 | -16,495 | -16,589 | -82,945 | -174,847 | -874,235 | -1,032,587 | -5,162,935 | -54,727,111 | -273,635,555 |
