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 1,050,245, 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 | 1,050,245 | |
| -1 | -1,050,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,050,245.
Example:
1 x 1,050,245 = 1,050,245
and
-1 x -1,050,245 = 1,050,245
Notice both answers equal 1,050,245
With that explanation out of the way, let's continue. Next, we take the number 1,050,245 and divide it by 2:
1,050,245 ÷ 2 = 525,122.5
If the quotient is a whole number, then 2 and 525,122.5 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 | 1,050,245 | |
| -1 | -1,050,245 |
Now, we try dividing 1,050,245 by 3:
1,050,245 ÷ 3 = 350,081.6667
If the quotient is a whole number, then 3 and 350,081.6667 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 | 1,050,245 | |
| -1 | -1,050,245 |
Let's try dividing by 4:
1,050,245 ÷ 4 = 262,561.25
If the quotient is a whole number, then 4 and 262,561.25 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 | 1,050,245 | |
| -1 | 1,050,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 811 | 1,295 | 4,055 | 5,677 | 28,385 | 30,007 | 150,035 | 210,049 | 1,050,245 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -811 | -1,295 | -4,055 | -5,677 | -28,385 | -30,007 | -150,035 | -210,049 | -1,050,245 |
