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 2,776,025, 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 | 2,776,025 | |
| -1 | -2,776,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,776,025.
Example:
1 x 2,776,025 = 2,776,025
and
-1 x -2,776,025 = 2,776,025
Notice both answers equal 2,776,025
With that explanation out of the way, let's continue. Next, we take the number 2,776,025 and divide it by 2:
2,776,025 ÷ 2 = 1,388,012.5
If the quotient is a whole number, then 2 and 1,388,012.5 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 | 2,776,025 | |
| -1 | -2,776,025 |
Now, we try dividing 2,776,025 by 3:
2,776,025 ÷ 3 = 925,341.6667
If the quotient is a whole number, then 3 and 925,341.6667 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 | 2,776,025 | |
| -1 | -2,776,025 |
Let's try dividing by 4:
2,776,025 ÷ 4 = 694,006.25
If the quotient is a whole number, then 4 and 694,006.25 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 | 2,776,025 | |
| -1 | 2,776,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 547 | 725 | 1,015 | 2,735 | 3,829 | 5,075 | 13,675 | 15,863 | 19,145 | 79,315 | 95,725 | 111,041 | 396,575 | 555,205 | 2,776,025 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -547 | -725 | -1,015 | -2,735 | -3,829 | -5,075 | -13,675 | -15,863 | -19,145 | -79,315 | -95,725 | -111,041 | -396,575 | -555,205 | -2,776,025 |
