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 1,201,085, 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 | 1,201,085 | |
| -1 | -1,201,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,201,085.
Example:
1 x 1,201,085 = 1,201,085
and
-1 x -1,201,085 = 1,201,085
Notice both answers equal 1,201,085
With that explanation out of the way, let's continue. Next, we take the number 1,201,085 and divide it by 2:
1,201,085 ÷ 2 = 600,542.5
If the quotient is a whole number, then 2 and 600,542.5 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 | 1,201,085 | |
| -1 | -1,201,085 |
Now, we try dividing 1,201,085 by 3:
1,201,085 ÷ 3 = 400,361.6667
If the quotient is a whole number, then 3 and 400,361.6667 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 | 1,201,085 | |
| -1 | -1,201,085 |
Let's try dividing by 4:
1,201,085 ÷ 4 = 300,271.25
If the quotient is a whole number, then 4 and 300,271.25 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 | 1,201,085 | |
| -1 | 1,201,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 47 | 95 | 235 | 269 | 893 | 1,345 | 4,465 | 5,111 | 12,643 | 25,555 | 63,215 | 240,217 | 1,201,085 |
| -1 | -5 | -19 | -47 | -95 | -235 | -269 | -893 | -1,345 | -4,465 | -5,111 | -12,643 | -25,555 | -63,215 | -240,217 | -1,201,085 |
