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 1,070,615, 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 | 1,070,615 | |
| -1 | -1,070,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,070,615.
Example:
1 x 1,070,615 = 1,070,615
and
-1 x -1,070,615 = 1,070,615
Notice both answers equal 1,070,615
With that explanation out of the way, let's continue. Next, we take the number 1,070,615 and divide it by 2:
1,070,615 ÷ 2 = 535,307.5
If the quotient is a whole number, then 2 and 535,307.5 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 | 1,070,615 | |
| -1 | -1,070,615 |
Now, we try dividing 1,070,615 by 3:
1,070,615 ÷ 3 = 356,871.6667
If the quotient is a whole number, then 3 and 356,871.6667 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 | 1,070,615 | |
| -1 | -1,070,615 |
Let's try dividing by 4:
1,070,615 ÷ 4 = 267,653.75
If the quotient is a whole number, then 4 and 267,653.75 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 | 1,070,615 | |
| -1 | 1,070,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 181 | 455 | 845 | 905 | 1,183 | 1,267 | 2,353 | 5,915 | 6,335 | 11,765 | 16,471 | 30,589 | 82,355 | 152,945 | 214,123 | 1,070,615 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -181 | -455 | -845 | -905 | -1,183 | -1,267 | -2,353 | -5,915 | -6,335 | -11,765 | -16,471 | -30,589 | -82,355 | -152,945 | -214,123 | -1,070,615 |
