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 270,845,239, 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 | 270,845,239 | |
| -1 | -270,845,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 270,845,239.
Example:
1 x 270,845,239 = 270,845,239
and
-1 x -270,845,239 = 270,845,239
Notice both answers equal 270,845,239
With that explanation out of the way, let's continue. Next, we take the number 270,845,239 and divide it by 2:
270,845,239 ÷ 2 = 135,422,619.5
If the quotient is a whole number, then 2 and 135,422,619.5 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 | 270,845,239 | |
| -1 | -270,845,239 |
Now, we try dividing 270,845,239 by 3:
270,845,239 ÷ 3 = 90,281,746.3333
If the quotient is a whole number, then 3 and 90,281,746.3333 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 | 270,845,239 | |
| -1 | -270,845,239 |
Let's try dividing by 4:
270,845,239 ÷ 4 = 67,711,309.75
If the quotient is a whole number, then 4 and 67,711,309.75 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 | 270,845,239 | |
| -1 | 270,845,239 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 883 | 1,511 | 6,181 | 10,577 | 25,607 | 43,819 | 179,249 | 306,733 | 1,334,213 | 9,339,491 | 38,692,177 | 270,845,239 |
| -1 | -7 | -29 | -203 | -883 | -1,511 | -6,181 | -10,577 | -25,607 | -43,819 | -179,249 | -306,733 | -1,334,213 | -9,339,491 | -38,692,177 | -270,845,239 |
