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 1,360,865, 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 | 1,360,865 | |
| -1 | -1,360,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,360,865.
Example:
1 x 1,360,865 = 1,360,865
and
-1 x -1,360,865 = 1,360,865
Notice both answers equal 1,360,865
With that explanation out of the way, let's continue. Next, we take the number 1,360,865 and divide it by 2:
1,360,865 ÷ 2 = 680,432.5
If the quotient is a whole number, then 2 and 680,432.5 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 | 1,360,865 | |
| -1 | -1,360,865 |
Now, we try dividing 1,360,865 by 3:
1,360,865 ÷ 3 = 453,621.6667
If the quotient is a whole number, then 3 and 453,621.6667 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 | 1,360,865 | |
| -1 | -1,360,865 |
Let's try dividing by 4:
1,360,865 ÷ 4 = 340,216.25
If the quotient is a whole number, then 4 and 340,216.25 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 | 1,360,865 | |
| -1 | 1,360,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 109 | 227 | 545 | 1,135 | 1,199 | 2,497 | 5,995 | 12,485 | 24,743 | 123,715 | 272,173 | 1,360,865 |
| -1 | -5 | -11 | -55 | -109 | -227 | -545 | -1,135 | -1,199 | -2,497 | -5,995 | -12,485 | -24,743 | -123,715 | -272,173 | -1,360,865 |
