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 277,025,177, 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 | 277,025,177 | |
| -1 | -277,025,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,025,177.
Example:
1 x 277,025,177 = 277,025,177
and
-1 x -277,025,177 = 277,025,177
Notice both answers equal 277,025,177
With that explanation out of the way, let's continue. Next, we take the number 277,025,177 and divide it by 2:
277,025,177 ÷ 2 = 138,512,588.5
If the quotient is a whole number, then 2 and 138,512,588.5 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 | 277,025,177 | |
| -1 | -277,025,177 |
Now, we try dividing 277,025,177 by 3:
277,025,177 ÷ 3 = 92,341,725.6667
If the quotient is a whole number, then 3 and 92,341,725.6667 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 | 277,025,177 | |
| -1 | -277,025,177 |
Let's try dividing by 4:
277,025,177 ÷ 4 = 69,256,294.25
If the quotient is a whole number, then 4 and 69,256,294.25 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 | 277,025,177 | |
| -1 | 277,025,177 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 443 | 4,373 | 4,873 | 5,759 | 48,103 | 56,849 | 63,349 | 625,339 | 1,937,239 | 21,309,629 | 25,184,107 | 277,025,177 |
| -1 | -11 | -13 | -143 | -443 | -4,373 | -4,873 | -5,759 | -48,103 | -56,849 | -63,349 | -625,339 | -1,937,239 | -21,309,629 | -25,184,107 | -277,025,177 |
