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 1,206,625, 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 | 1,206,625 | |
| -1 | -1,206,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,206,625.
Example:
1 x 1,206,625 = 1,206,625
and
-1 x -1,206,625 = 1,206,625
Notice both answers equal 1,206,625
With that explanation out of the way, let's continue. Next, we take the number 1,206,625 and divide it by 2:
1,206,625 ÷ 2 = 603,312.5
If the quotient is a whole number, then 2 and 603,312.5 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 | 1,206,625 | |
| -1 | -1,206,625 |
Now, we try dividing 1,206,625 by 3:
1,206,625 ÷ 3 = 402,208.3333
If the quotient is a whole number, then 3 and 402,208.3333 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 | 1,206,625 | |
| -1 | -1,206,625 |
Let's try dividing by 4:
1,206,625 ÷ 4 = 301,656.25
If the quotient is a whole number, then 4 and 301,656.25 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 | 1,206,625 | |
| -1 | 1,206,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 125 | 175 | 197 | 245 | 875 | 985 | 1,225 | 1,379 | 4,925 | 6,125 | 6,895 | 9,653 | 24,625 | 34,475 | 48,265 | 172,375 | 241,325 | 1,206,625 |
| -1 | -5 | -7 | -25 | -35 | -49 | -125 | -175 | -197 | -245 | -875 | -985 | -1,225 | -1,379 | -4,925 | -6,125 | -6,895 | -9,653 | -24,625 | -34,475 | -48,265 | -172,375 | -241,325 | -1,206,625 |
