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 272,632,835, 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 | 272,632,835 | |
| -1 | -272,632,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,632,835.
Example:
1 x 272,632,835 = 272,632,835
and
-1 x -272,632,835 = 272,632,835
Notice both answers equal 272,632,835
With that explanation out of the way, let's continue. Next, we take the number 272,632,835 and divide it by 2:
272,632,835 ÷ 2 = 136,316,417.5
If the quotient is a whole number, then 2 and 136,316,417.5 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 | 272,632,835 | |
| -1 | -272,632,835 |
Now, we try dividing 272,632,835 by 3:
272,632,835 ÷ 3 = 90,877,611.6667
If the quotient is a whole number, then 3 and 90,877,611.6667 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 | 272,632,835 | |
| -1 | -272,632,835 |
Let's try dividing by 4:
272,632,835 ÷ 4 = 68,158,208.75
If the quotient is a whole number, then 4 and 68,158,208.75 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 | 272,632,835 | |
| -1 | 272,632,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 101 | 185 | 505 | 3,737 | 14,591 | 18,685 | 72,955 | 539,867 | 1,473,691 | 2,699,335 | 7,368,455 | 54,526,567 | 272,632,835 |
| -1 | -5 | -37 | -101 | -185 | -505 | -3,737 | -14,591 | -18,685 | -72,955 | -539,867 | -1,473,691 | -2,699,335 | -7,368,455 | -54,526,567 | -272,632,835 |
