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 12,946,741, 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 | 12,946,741 | |
| -1 | -12,946,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,946,741.
Example:
1 x 12,946,741 = 12,946,741
and
-1 x -12,946,741 = 12,946,741
Notice both answers equal 12,946,741
With that explanation out of the way, let's continue. Next, we take the number 12,946,741 and divide it by 2:
12,946,741 ÷ 2 = 6,473,370.5
If the quotient is a whole number, then 2 and 6,473,370.5 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 | 12,946,741 | |
| -1 | -12,946,741 |
Now, we try dividing 12,946,741 by 3:
12,946,741 ÷ 3 = 4,315,580.3333
If the quotient is a whole number, then 3 and 4,315,580.3333 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 | 12,946,741 | |
| -1 | -12,946,741 |
Let's try dividing by 4:
12,946,741 ÷ 4 = 3,236,685.25
If the quotient is a whole number, then 4 and 3,236,685.25 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 | 12,946,741 | |
| -1 | 12,946,741 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 89 | 199 | 731 | 1,513 | 3,383 | 3,827 | 8,557 | 17,711 | 65,059 | 145,469 | 301,087 | 761,573 | 12,946,741 |
| -1 | -17 | -43 | -89 | -199 | -731 | -1,513 | -3,383 | -3,827 | -8,557 | -17,711 | -65,059 | -145,469 | -301,087 | -761,573 | -12,946,741 |
