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 270,686,575, 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 | 270,686,575 | |
| -1 | -270,686,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 270,686,575.
Example:
1 x 270,686,575 = 270,686,575
and
-1 x -270,686,575 = 270,686,575
Notice both answers equal 270,686,575
With that explanation out of the way, let's continue. Next, we take the number 270,686,575 and divide it by 2:
270,686,575 ÷ 2 = 135,343,287.5
If the quotient is a whole number, then 2 and 135,343,287.5 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 | 270,686,575 | |
| -1 | -270,686,575 |
Now, we try dividing 270,686,575 by 3:
270,686,575 ÷ 3 = 90,228,858.3333
If the quotient is a whole number, then 3 and 90,228,858.3333 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 | 270,686,575 | |
| -1 | -270,686,575 |
Let's try dividing by 4:
270,686,575 ÷ 4 = 67,671,643.75
If the quotient is a whole number, then 4 and 67,671,643.75 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 | 270,686,575 | |
| -1 | 270,686,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 103 | 155 | 515 | 775 | 2,575 | 3,193 | 3,391 | 15,965 | 16,955 | 79,825 | 84,775 | 105,121 | 349,273 | 525,605 | 1,746,365 | 2,628,025 | 8,731,825 | 10,827,463 | 54,137,315 | 270,686,575 |
| -1 | -5 | -25 | -31 | -103 | -155 | -515 | -775 | -2,575 | -3,193 | -3,391 | -15,965 | -16,955 | -79,825 | -84,775 | -105,121 | -349,273 | -525,605 | -1,746,365 | -2,628,025 | -8,731,825 | -10,827,463 | -54,137,315 | -270,686,575 |
