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 1,206,275, 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 | 1,206,275 | |
| -1 | -1,206,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,206,275.
Example:
1 x 1,206,275 = 1,206,275
and
-1 x -1,206,275 = 1,206,275
Notice both answers equal 1,206,275
With that explanation out of the way, let's continue. Next, we take the number 1,206,275 and divide it by 2:
1,206,275 ÷ 2 = 603,137.5
If the quotient is a whole number, then 2 and 603,137.5 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 | 1,206,275 | |
| -1 | -1,206,275 |
Now, we try dividing 1,206,275 by 3:
1,206,275 ÷ 3 = 402,091.6667
If the quotient is a whole number, then 3 and 402,091.6667 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 | 1,206,275 | |
| -1 | -1,206,275 |
Let's try dividing by 4:
1,206,275 ÷ 4 = 301,568.75
If the quotient is a whole number, then 4 and 301,568.75 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 | 1,206,275 | |
| -1 | 1,206,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 61 | 113 | 175 | 305 | 427 | 565 | 791 | 1,525 | 2,135 | 2,825 | 3,955 | 6,893 | 10,675 | 19,775 | 34,465 | 48,251 | 172,325 | 241,255 | 1,206,275 |
| -1 | -5 | -7 | -25 | -35 | -61 | -113 | -175 | -305 | -427 | -565 | -791 | -1,525 | -2,135 | -2,825 | -3,955 | -6,893 | -10,675 | -19,775 | -34,465 | -48,251 | -172,325 | -241,255 | -1,206,275 |
