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 277,265,677, 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 | 277,265,677 | |
| -1 | -277,265,677 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,265,677.
Example:
1 x 277,265,677 = 277,265,677
and
-1 x -277,265,677 = 277,265,677
Notice both answers equal 277,265,677
With that explanation out of the way, let's continue. Next, we take the number 277,265,677 and divide it by 2:
277,265,677 ÷ 2 = 138,632,838.5
If the quotient is a whole number, then 2 and 138,632,838.5 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 | 277,265,677 | |
| -1 | -277,265,677 |
Now, we try dividing 277,265,677 by 3:
277,265,677 ÷ 3 = 92,421,892.3333
If the quotient is a whole number, then 3 and 92,421,892.3333 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 | 277,265,677 | |
| -1 | -277,265,677 |
Let's try dividing by 4:
277,265,677 ÷ 4 = 69,316,419.25
If the quotient is a whole number, then 4 and 69,316,419.25 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 | 277,265,677 | |
| -1 | 277,265,677 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 559 | 563 | 881 | 7,319 | 11,453 | 24,209 | 37,883 | 314,717 | 492,479 | 496,003 | 6,448,039 | 21,328,129 | 277,265,677 |
| -1 | -13 | -43 | -559 | -563 | -881 | -7,319 | -11,453 | -24,209 | -37,883 | -314,717 | -492,479 | -496,003 | -6,448,039 | -21,328,129 | -277,265,677 |
