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 12,276,005, 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 | 12,276,005 | |
| -1 | -12,276,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,276,005.
Example:
1 x 12,276,005 = 12,276,005
and
-1 x -12,276,005 = 12,276,005
Notice both answers equal 12,276,005
With that explanation out of the way, let's continue. Next, we take the number 12,276,005 and divide it by 2:
12,276,005 ÷ 2 = 6,138,002.5
If the quotient is a whole number, then 2 and 6,138,002.5 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 | 12,276,005 | |
| -1 | -12,276,005 |
Now, we try dividing 12,276,005 by 3:
12,276,005 ÷ 3 = 4,092,001.6667
If the quotient is a whole number, then 3 and 4,092,001.6667 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 | 12,276,005 | |
| -1 | -12,276,005 |
Let's try dividing by 4:
12,276,005 ÷ 4 = 3,069,001.25
If the quotient is a whole number, then 4 and 3,069,001.25 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 | 12,276,005 | |
| -1 | 12,276,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 359 | 977 | 1,795 | 2,513 | 4,885 | 6,839 | 12,565 | 34,195 | 350,743 | 1,753,715 | 2,455,201 | 12,276,005 |
| -1 | -5 | -7 | -35 | -359 | -977 | -1,795 | -2,513 | -4,885 | -6,839 | -12,565 | -34,195 | -350,743 | -1,753,715 | -2,455,201 | -12,276,005 |
