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 1,051,715, 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 | 1,051,715 | |
| -1 | -1,051,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,051,715.
Example:
1 x 1,051,715 = 1,051,715
and
-1 x -1,051,715 = 1,051,715
Notice both answers equal 1,051,715
With that explanation out of the way, let's continue. Next, we take the number 1,051,715 and divide it by 2:
1,051,715 ÷ 2 = 525,857.5
If the quotient is a whole number, then 2 and 525,857.5 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 | 1,051,715 | |
| -1 | -1,051,715 |
Now, we try dividing 1,051,715 by 3:
1,051,715 ÷ 3 = 350,571.6667
If the quotient is a whole number, then 3 and 350,571.6667 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 | 1,051,715 | |
| -1 | -1,051,715 |
Let's try dividing by 4:
1,051,715 ÷ 4 = 262,928.75
If the quotient is a whole number, then 4 and 262,928.75 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 | 1,051,715 | |
| -1 | 1,051,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 151 | 199 | 755 | 995 | 1,057 | 1,393 | 5,285 | 6,965 | 30,049 | 150,245 | 210,343 | 1,051,715 |
| -1 | -5 | -7 | -35 | -151 | -199 | -755 | -995 | -1,057 | -1,393 | -5,285 | -6,965 | -30,049 | -150,245 | -210,343 | -1,051,715 |
