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 10,777,415, 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 | 10,777,415 | |
| -1 | -10,777,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,777,415.
Example:
1 x 10,777,415 = 10,777,415
and
-1 x -10,777,415 = 10,777,415
Notice both answers equal 10,777,415
With that explanation out of the way, let's continue. Next, we take the number 10,777,415 and divide it by 2:
10,777,415 ÷ 2 = 5,388,707.5
If the quotient is a whole number, then 2 and 5,388,707.5 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 | 10,777,415 | |
| -1 | -10,777,415 |
Now, we try dividing 10,777,415 by 3:
10,777,415 ÷ 3 = 3,592,471.6667
If the quotient is a whole number, then 3 and 3,592,471.6667 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 | 10,777,415 | |
| -1 | -10,777,415 |
Let's try dividing by 4:
10,777,415 ÷ 4 = 2,694,353.75
If the quotient is a whole number, then 4 and 2,694,353.75 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 | 10,777,415 | |
| -1 | 10,777,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 233 | 319 | 841 | 1,165 | 1,595 | 2,563 | 4,205 | 6,757 | 9,251 | 12,815 | 33,785 | 46,255 | 74,327 | 195,953 | 371,635 | 979,765 | 2,155,483 | 10,777,415 |
| -1 | -5 | -11 | -29 | -55 | -145 | -233 | -319 | -841 | -1,165 | -1,595 | -2,563 | -4,205 | -6,757 | -9,251 | -12,815 | -33,785 | -46,255 | -74,327 | -195,953 | -371,635 | -979,765 | -2,155,483 | -10,777,415 |
