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 1,405,775, 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 | 1,405,775 | |
| -1 | -1,405,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,405,775.
Example:
1 x 1,405,775 = 1,405,775
and
-1 x -1,405,775 = 1,405,775
Notice both answers equal 1,405,775
With that explanation out of the way, let's continue. Next, we take the number 1,405,775 and divide it by 2:
1,405,775 ÷ 2 = 702,887.5
If the quotient is a whole number, then 2 and 702,887.5 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 | 1,405,775 | |
| -1 | -1,405,775 |
Now, we try dividing 1,405,775 by 3:
1,405,775 ÷ 3 = 468,591.6667
If the quotient is a whole number, then 3 and 468,591.6667 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 | 1,405,775 | |
| -1 | -1,405,775 |
Let's try dividing by 4:
1,405,775 ÷ 4 = 351,443.75
If the quotient is a whole number, then 4 and 351,443.75 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 | 1,405,775 | |
| -1 | 1,405,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 277 | 725 | 1,015 | 1,385 | 1,939 | 5,075 | 6,925 | 8,033 | 9,695 | 40,165 | 48,475 | 56,231 | 200,825 | 281,155 | 1,405,775 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -277 | -725 | -1,015 | -1,385 | -1,939 | -5,075 | -6,925 | -8,033 | -9,695 | -40,165 | -48,475 | -56,231 | -200,825 | -281,155 | -1,405,775 |
