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 1,009,925, 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 | 1,009,925 | |
| -1 | -1,009,925 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,009,925.
Example:
1 x 1,009,925 = 1,009,925
and
-1 x -1,009,925 = 1,009,925
Notice both answers equal 1,009,925
With that explanation out of the way, let's continue. Next, we take the number 1,009,925 and divide it by 2:
1,009,925 ÷ 2 = 504,962.5
If the quotient is a whole number, then 2 and 504,962.5 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 | 1,009,925 | |
| -1 | -1,009,925 |
Now, we try dividing 1,009,925 by 3:
1,009,925 ÷ 3 = 336,641.6667
If the quotient is a whole number, then 3 and 336,641.6667 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 | 1,009,925 | |
| -1 | -1,009,925 |
Let's try dividing by 4:
1,009,925 ÷ 4 = 252,481.25
If the quotient is a whole number, then 4 and 252,481.25 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 | 1,009,925 | |
| -1 | 1,009,925 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 199 | 203 | 725 | 995 | 1,015 | 1,393 | 4,975 | 5,075 | 5,771 | 6,965 | 28,855 | 34,825 | 40,397 | 144,275 | 201,985 | 1,009,925 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -199 | -203 | -725 | -995 | -1,015 | -1,393 | -4,975 | -5,075 | -5,771 | -6,965 | -28,855 | -34,825 | -40,397 | -144,275 | -201,985 | -1,009,925 |
