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 1,776,925, 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 | 1,776,925 | |
| -1 | -1,776,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,776,925.
Example:
1 x 1,776,925 = 1,776,925
and
-1 x -1,776,925 = 1,776,925
Notice both answers equal 1,776,925
With that explanation out of the way, let's continue. Next, we take the number 1,776,925 and divide it by 2:
1,776,925 ÷ 2 = 888,462.5
If the quotient is a whole number, then 2 and 888,462.5 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 | 1,776,925 | |
| -1 | -1,776,925 |
Now, we try dividing 1,776,925 by 3:
1,776,925 ÷ 3 = 592,308.3333
If the quotient is a whole number, then 3 and 592,308.3333 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 | 1,776,925 | |
| -1 | -1,776,925 |
Let's try dividing by 4:
1,776,925 ÷ 4 = 444,231.25
If the quotient is a whole number, then 4 and 444,231.25 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 | 1,776,925 | |
| -1 | 1,776,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 37 | 85 | 113 | 185 | 425 | 565 | 629 | 925 | 1,921 | 2,825 | 3,145 | 4,181 | 9,605 | 15,725 | 20,905 | 48,025 | 71,077 | 104,525 | 355,385 | 1,776,925 |
| -1 | -5 | -17 | -25 | -37 | -85 | -113 | -185 | -425 | -565 | -629 | -925 | -1,921 | -2,825 | -3,145 | -4,181 | -9,605 | -15,725 | -20,905 | -48,025 | -71,077 | -104,525 | -355,385 | -1,776,925 |
