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 275,176,565, 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 | 275,176,565 | |
| -1 | -275,176,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 275,176,565.
Example:
1 x 275,176,565 = 275,176,565
and
-1 x -275,176,565 = 275,176,565
Notice both answers equal 275,176,565
With that explanation out of the way, let's continue. Next, we take the number 275,176,565 and divide it by 2:
275,176,565 ÷ 2 = 137,588,282.5
If the quotient is a whole number, then 2 and 137,588,282.5 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 | 275,176,565 | |
| -1 | -275,176,565 |
Now, we try dividing 275,176,565 by 3:
275,176,565 ÷ 3 = 91,725,521.6667
If the quotient is a whole number, then 3 and 91,725,521.6667 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 | 275,176,565 | |
| -1 | -275,176,565 |
Let's try dividing by 4:
275,176,565 ÷ 4 = 68,794,141.25
If the quotient is a whole number, then 4 and 68,794,141.25 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 | 275,176,565 | |
| -1 | 275,176,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 191 | 215 | 955 | 6,701 | 8,213 | 33,505 | 41,065 | 288,143 | 1,279,891 | 1,440,715 | 6,399,455 | 55,035,313 | 275,176,565 |
| -1 | -5 | -43 | -191 | -215 | -955 | -6,701 | -8,213 | -33,505 | -41,065 | -288,143 | -1,279,891 | -1,440,715 | -6,399,455 | -55,035,313 | -275,176,565 |
