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 277,025,179, 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 | 277,025,179 | |
| -1 | -277,025,179 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,025,179.
Example:
1 x 277,025,179 = 277,025,179
and
-1 x -277,025,179 = 277,025,179
Notice both answers equal 277,025,179
With that explanation out of the way, let's continue. Next, we take the number 277,025,179 and divide it by 2:
277,025,179 ÷ 2 = 138,512,589.5
If the quotient is a whole number, then 2 and 138,512,589.5 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 | 277,025,179 | |
| -1 | -277,025,179 |
Now, we try dividing 277,025,179 by 3:
277,025,179 ÷ 3 = 92,341,726.3333
If the quotient is a whole number, then 3 and 92,341,726.3333 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 | 277,025,179 | |
| -1 | -277,025,179 |
Let's try dividing by 4:
277,025,179 ÷ 4 = 69,256,294.75
If the quotient is a whole number, then 4 and 69,256,294.75 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 | 277,025,179 | |
| -1 | 277,025,179 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 367 | 851 | 887 | 8,441 | 13,579 | 20,401 | 32,819 | 312,317 | 325,529 | 754,837 | 7,487,167 | 12,044,573 | 277,025,179 |
| -1 | -23 | -37 | -367 | -851 | -887 | -8,441 | -13,579 | -20,401 | -32,819 | -312,317 | -325,529 | -754,837 | -7,487,167 | -12,044,573 | -277,025,179 |
