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 277,551,265, 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 | 277,551,265 | |
| -1 | -277,551,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,551,265.
Example:
1 x 277,551,265 = 277,551,265
and
-1 x -277,551,265 = 277,551,265
Notice both answers equal 277,551,265
With that explanation out of the way, let's continue. Next, we take the number 277,551,265 and divide it by 2:
277,551,265 ÷ 2 = 138,775,632.5
If the quotient is a whole number, then 2 and 138,775,632.5 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 | 277,551,265 | |
| -1 | -277,551,265 |
Now, we try dividing 277,551,265 by 3:
277,551,265 ÷ 3 = 92,517,088.3333
If the quotient is a whole number, then 3 and 92,517,088.3333 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 | 277,551,265 | |
| -1 | -277,551,265 |
Let's try dividing by 4:
277,551,265 ÷ 4 = 69,387,816.25
If the quotient is a whole number, then 4 and 69,387,816.25 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 | 277,551,265 | |
| -1 | 277,551,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 241 | 289 | 797 | 1,205 | 1,445 | 3,985 | 4,097 | 13,549 | 20,485 | 67,745 | 69,649 | 192,077 | 230,333 | 348,245 | 960,385 | 1,151,665 | 3,265,309 | 16,326,545 | 55,510,253 | 277,551,265 |
| -1 | -5 | -17 | -85 | -241 | -289 | -797 | -1,205 | -1,445 | -3,985 | -4,097 | -13,549 | -20,485 | -67,745 | -69,649 | -192,077 | -230,333 | -348,245 | -960,385 | -1,151,665 | -3,265,309 | -16,326,545 | -55,510,253 | -277,551,265 |
