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 2,075,755, 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 | 2,075,755 | |
| -1 | -2,075,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,075,755.
Example:
1 x 2,075,755 = 2,075,755
and
-1 x -2,075,755 = 2,075,755
Notice both answers equal 2,075,755
With that explanation out of the way, let's continue. Next, we take the number 2,075,755 and divide it by 2:
2,075,755 ÷ 2 = 1,037,877.5
If the quotient is a whole number, then 2 and 1,037,877.5 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 | 2,075,755 | |
| -1 | -2,075,755 |
Now, we try dividing 2,075,755 by 3:
2,075,755 ÷ 3 = 691,918.3333
If the quotient is a whole number, then 3 and 691,918.3333 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 | 2,075,755 | |
| -1 | -2,075,755 |
Let's try dividing by 4:
2,075,755 ÷ 4 = 518,938.75
If the quotient is a whole number, then 4 and 518,938.75 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 | 2,075,755 | |
| -1 | 2,075,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 73 | 121 | 235 | 365 | 517 | 605 | 803 | 2,585 | 3,431 | 4,015 | 5,687 | 8,833 | 17,155 | 28,435 | 37,741 | 44,165 | 188,705 | 415,151 | 2,075,755 |
| -1 | -5 | -11 | -47 | -55 | -73 | -121 | -235 | -365 | -517 | -605 | -803 | -2,585 | -3,431 | -4,015 | -5,687 | -8,833 | -17,155 | -28,435 | -37,741 | -44,165 | -188,705 | -415,151 | -2,075,755 |
