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 1,203,265, 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 | 1,203,265 | |
| -1 | -1,203,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,203,265.
Example:
1 x 1,203,265 = 1,203,265
and
-1 x -1,203,265 = 1,203,265
Notice both answers equal 1,203,265
With that explanation out of the way, let's continue. Next, we take the number 1,203,265 and divide it by 2:
1,203,265 ÷ 2 = 601,632.5
If the quotient is a whole number, then 2 and 601,632.5 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 | 1,203,265 | |
| -1 | -1,203,265 |
Now, we try dividing 1,203,265 by 3:
1,203,265 ÷ 3 = 401,088.3333
If the quotient is a whole number, then 3 and 401,088.3333 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 | 1,203,265 | |
| -1 | -1,203,265 |
Let's try dividing by 4:
1,203,265 ÷ 4 = 300,816.25
If the quotient is a whole number, then 4 and 300,816.25 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 | 1,203,265 | |
| -1 | 1,203,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 1,109 | 5,545 | 7,763 | 34,379 | 38,815 | 171,895 | 240,653 | 1,203,265 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -1,109 | -5,545 | -7,763 | -34,379 | -38,815 | -171,895 | -240,653 | -1,203,265 |
