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 12,963,629, 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 | 12,963,629 | |
| -1 | -12,963,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,963,629.
Example:
1 x 12,963,629 = 12,963,629
and
-1 x -12,963,629 = 12,963,629
Notice both answers equal 12,963,629
With that explanation out of the way, let's continue. Next, we take the number 12,963,629 and divide it by 2:
12,963,629 ÷ 2 = 6,481,814.5
If the quotient is a whole number, then 2 and 6,481,814.5 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 | 12,963,629 | |
| -1 | -12,963,629 |
Now, we try dividing 12,963,629 by 3:
12,963,629 ÷ 3 = 4,321,209.6667
If the quotient is a whole number, then 3 and 4,321,209.6667 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 | 12,963,629 | |
| -1 | -12,963,629 |
Let's try dividing by 4:
12,963,629 ÷ 4 = 3,240,907.25
If the quotient is a whole number, then 4 and 3,240,907.25 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 | 12,963,629 | |
| -1 | 12,963,629 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 131 | 211 | 469 | 917 | 1,477 | 8,777 | 14,137 | 27,641 | 61,439 | 98,959 | 193,487 | 1,851,947 | 12,963,629 |
| -1 | -7 | -67 | -131 | -211 | -469 | -917 | -1,477 | -8,777 | -14,137 | -27,641 | -61,439 | -98,959 | -193,487 | -1,851,947 | -12,963,629 |
