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 277,175,255, 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 | 277,175,255 | |
| -1 | -277,175,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,175,255.
Example:
1 x 277,175,255 = 277,175,255
and
-1 x -277,175,255 = 277,175,255
Notice both answers equal 277,175,255
With that explanation out of the way, let's continue. Next, we take the number 277,175,255 and divide it by 2:
277,175,255 ÷ 2 = 138,587,627.5
If the quotient is a whole number, then 2 and 138,587,627.5 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 | 277,175,255 | |
| -1 | -277,175,255 |
Now, we try dividing 277,175,255 by 3:
277,175,255 ÷ 3 = 92,391,751.6667
If the quotient is a whole number, then 3 and 92,391,751.6667 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 | 277,175,255 | |
| -1 | -277,175,255 |
Let's try dividing by 4:
277,175,255 ÷ 4 = 69,293,813.75
If the quotient is a whole number, then 4 and 69,293,813.75 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 | 277,175,255 | |
| -1 | 277,175,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 181 | 905 | 1,267 | 6,335 | 43,753 | 218,765 | 306,271 | 1,531,355 | 7,919,293 | 39,596,465 | 55,435,051 | 277,175,255 |
| -1 | -5 | -7 | -35 | -181 | -905 | -1,267 | -6,335 | -43,753 | -218,765 | -306,271 | -1,531,355 | -7,919,293 | -39,596,465 | -55,435,051 | -277,175,255 |
