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 277,678,795, 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 | 277,678,795 | |
| -1 | -277,678,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,678,795.
Example:
1 x 277,678,795 = 277,678,795
and
-1 x -277,678,795 = 277,678,795
Notice both answers equal 277,678,795
With that explanation out of the way, let's continue. Next, we take the number 277,678,795 and divide it by 2:
277,678,795 ÷ 2 = 138,839,397.5
If the quotient is a whole number, then 2 and 138,839,397.5 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 | 277,678,795 | |
| -1 | -277,678,795 |
Now, we try dividing 277,678,795 by 3:
277,678,795 ÷ 3 = 92,559,598.3333
If the quotient is a whole number, then 3 and 92,559,598.3333 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 | 277,678,795 | |
| -1 | -277,678,795 |
Let's try dividing by 4:
277,678,795 ÷ 4 = 69,419,698.75
If the quotient is a whole number, then 4 and 69,419,698.75 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 | 277,678,795 | |
| -1 | 277,678,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 271 | 505 | 1,355 | 2,029 | 10,145 | 27,371 | 136,855 | 204,929 | 549,859 | 1,024,645 | 2,749,295 | 55,535,759 | 277,678,795 |
| -1 | -5 | -101 | -271 | -505 | -1,355 | -2,029 | -10,145 | -27,371 | -136,855 | -204,929 | -549,859 | -1,024,645 | -2,749,295 | -55,535,759 | -277,678,795 |
