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 277,126,003, 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 | 277,126,003 | |
| -1 | -277,126,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,126,003.
Example:
1 x 277,126,003 = 277,126,003
and
-1 x -277,126,003 = 277,126,003
Notice both answers equal 277,126,003
With that explanation out of the way, let's continue. Next, we take the number 277,126,003 and divide it by 2:
277,126,003 ÷ 2 = 138,563,001.5
If the quotient is a whole number, then 2 and 138,563,001.5 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 | 277,126,003 | |
| -1 | -277,126,003 |
Now, we try dividing 277,126,003 by 3:
277,126,003 ÷ 3 = 92,375,334.3333
If the quotient is a whole number, then 3 and 92,375,334.3333 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 | 277,126,003 | |
| -1 | -277,126,003 |
Let's try dividing by 4:
277,126,003 ÷ 4 = 69,281,500.75
If the quotient is a whole number, then 4 and 69,281,500.75 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 | 277,126,003 | |
| -1 | 277,126,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 737 | 5,159 | 53,717 | 376,019 | 590,887 | 3,599,039 | 4,136,209 | 25,193,273 | 39,589,429 | 277,126,003 |
| -1 | -7 | -11 | -67 | -77 | -469 | -737 | -5,159 | -53,717 | -376,019 | -590,887 | -3,599,039 | -4,136,209 | -25,193,273 | -39,589,429 | -277,126,003 |
