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 1,225,063, 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 | 1,225,063 | |
| -1 | -1,225,063 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,225,063.
Example:
1 x 1,225,063 = 1,225,063
and
-1 x -1,225,063 = 1,225,063
Notice both answers equal 1,225,063
With that explanation out of the way, let's continue. Next, we take the number 1,225,063 and divide it by 2:
1,225,063 ÷ 2 = 612,531.5
If the quotient is a whole number, then 2 and 612,531.5 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 | 1,225,063 | |
| -1 | -1,225,063 |
Now, we try dividing 1,225,063 by 3:
1,225,063 ÷ 3 = 408,354.3333
If the quotient is a whole number, then 3 and 408,354.3333 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 | 1,225,063 | |
| -1 | -1,225,063 |
Let's try dividing by 4:
1,225,063 ÷ 4 = 306,265.75
If the quotient is a whole number, then 4 and 306,265.75 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 | 1,225,063 | |
| -1 | 1,225,063 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 61 | 133 | 151 | 427 | 1,057 | 1,159 | 2,869 | 8,113 | 9,211 | 20,083 | 64,477 | 175,009 | 1,225,063 |
| -1 | -7 | -19 | -61 | -133 | -151 | -427 | -1,057 | -1,159 | -2,869 | -8,113 | -9,211 | -20,083 | -64,477 | -175,009 | -1,225,063 |
