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 12,061,465, 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 | 12,061,465 | |
| -1 | -12,061,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,061,465.
Example:
1 x 12,061,465 = 12,061,465
and
-1 x -12,061,465 = 12,061,465
Notice both answers equal 12,061,465
With that explanation out of the way, let's continue. Next, we take the number 12,061,465 and divide it by 2:
12,061,465 ÷ 2 = 6,030,732.5
If the quotient is a whole number, then 2 and 6,030,732.5 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 | 12,061,465 | |
| -1 | -12,061,465 |
Now, we try dividing 12,061,465 by 3:
12,061,465 ÷ 3 = 4,020,488.3333
If the quotient is a whole number, then 3 and 4,020,488.3333 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 | 12,061,465 | |
| -1 | -12,061,465 |
Let's try dividing by 4:
12,061,465 ÷ 4 = 3,015,366.25
If the quotient is a whole number, then 4 and 3,015,366.25 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 | 12,061,465 | |
| -1 | 12,061,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 97 | 485 | 1,261 | 1,913 | 6,305 | 9,565 | 24,869 | 124,345 | 185,561 | 927,805 | 2,412,293 | 12,061,465 |
| -1 | -5 | -13 | -65 | -97 | -485 | -1,261 | -1,913 | -6,305 | -9,565 | -24,869 | -124,345 | -185,561 | -927,805 | -2,412,293 | -12,061,465 |
