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 277,702,463, 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 | 277,702,463 | |
| -1 | -277,702,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,702,463.
Example:
1 x 277,702,463 = 277,702,463
and
-1 x -277,702,463 = 277,702,463
Notice both answers equal 277,702,463
With that explanation out of the way, let's continue. Next, we take the number 277,702,463 and divide it by 2:
277,702,463 ÷ 2 = 138,851,231.5
If the quotient is a whole number, then 2 and 138,851,231.5 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 | 277,702,463 | |
| -1 | -277,702,463 |
Now, we try dividing 277,702,463 by 3:
277,702,463 ÷ 3 = 92,567,487.6667
If the quotient is a whole number, then 3 and 92,567,487.6667 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 | 277,702,463 | |
| -1 | -277,702,463 |
Let's try dividing by 4:
277,702,463 ÷ 4 = 69,425,615.75
If the quotient is a whole number, then 4 and 69,425,615.75 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 | 277,702,463 | |
| -1 | 277,702,463 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 167 | 493 | 2,839 | 3,373 | 4,843 | 57,341 | 82,331 | 97,817 | 563,291 | 1,662,889 | 9,575,947 | 16,335,439 | 277,702,463 |
| -1 | -17 | -29 | -167 | -493 | -2,839 | -3,373 | -4,843 | -57,341 | -82,331 | -97,817 | -563,291 | -1,662,889 | -9,575,947 | -16,335,439 | -277,702,463 |
