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 277,441,003, 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 | 277,441,003 | |
| -1 | -277,441,003 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,441,003.
Example:
1 x 277,441,003 = 277,441,003
and
-1 x -277,441,003 = 277,441,003
Notice both answers equal 277,441,003
With that explanation out of the way, let's continue. Next, we take the number 277,441,003 and divide it by 2:
277,441,003 ÷ 2 = 138,720,501.5
If the quotient is a whole number, then 2 and 138,720,501.5 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 | 277,441,003 | |
| -1 | -277,441,003 |
Now, we try dividing 277,441,003 by 3:
277,441,003 ÷ 3 = 92,480,334.3333
If the quotient is a whole number, then 3 and 92,480,334.3333 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 | 277,441,003 | |
| -1 | -277,441,003 |
Let's try dividing by 4:
277,441,003 ÷ 4 = 69,360,250.75
If the quotient is a whole number, then 4 and 69,360,250.75 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 | 277,441,003 | |
| -1 | 277,441,003 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 967 | 2,411 | 6,769 | 16,439 | 16,877 | 40,987 | 115,073 | 286,909 | 2,331,437 | 16,320,059 | 39,634,429 | 277,441,003 |
| -1 | -7 | -17 | -119 | -967 | -2,411 | -6,769 | -16,439 | -16,877 | -40,987 | -115,073 | -286,909 | -2,331,437 | -16,320,059 | -39,634,429 | -277,441,003 |
