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 277,144,445, 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 | 277,144,445 | |
| -1 | -277,144,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 277,144,445.
Example:
1 x 277,144,445 = 277,144,445
and
-1 x -277,144,445 = 277,144,445
Notice both answers equal 277,144,445
With that explanation out of the way, let's continue. Next, we take the number 277,144,445 and divide it by 2:
277,144,445 ÷ 2 = 138,572,222.5
If the quotient is a whole number, then 2 and 138,572,222.5 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 | 277,144,445 | |
| -1 | -277,144,445 |
Now, we try dividing 277,144,445 by 3:
277,144,445 ÷ 3 = 92,381,481.6667
If the quotient is a whole number, then 3 and 92,381,481.6667 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 | 277,144,445 | |
| -1 | -277,144,445 |
Let's try dividing by 4:
277,144,445 ÷ 4 = 69,286,111.25
If the quotient is a whole number, then 4 and 69,286,111.25 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 | 277,144,445 | |
| -1 | 277,144,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 107 | 145 | 535 | 3,103 | 15,515 | 17,863 | 89,315 | 518,027 | 1,911,341 | 2,590,135 | 9,556,705 | 55,428,889 | 277,144,445 |
| -1 | -5 | -29 | -107 | -145 | -535 | -3,103 | -15,515 | -17,863 | -89,315 | -518,027 | -1,911,341 | -2,590,135 | -9,556,705 | -55,428,889 | -277,144,445 |
