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 12,465,937, 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 | 12,465,937 | |
| -1 | -12,465,937 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,465,937.
Example:
1 x 12,465,937 = 12,465,937
and
-1 x -12,465,937 = 12,465,937
Notice both answers equal 12,465,937
With that explanation out of the way, let's continue. Next, we take the number 12,465,937 and divide it by 2:
12,465,937 ÷ 2 = 6,232,968.5
If the quotient is a whole number, then 2 and 6,232,968.5 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 | 12,465,937 | |
| -1 | -12,465,937 |
Now, we try dividing 12,465,937 by 3:
12,465,937 ÷ 3 = 4,155,312.3333
If the quotient is a whole number, then 3 and 4,155,312.3333 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 | 12,465,937 | |
| -1 | -12,465,937 |
Let's try dividing by 4:
12,465,937 ÷ 4 = 3,116,484.25
If the quotient is a whole number, then 4 and 3,116,484.25 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 | 12,465,937 | |
| -1 | 12,465,937 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 139 | 263 | 341 | 1,529 | 2,893 | 4,309 | 8,153 | 36,557 | 47,399 | 89,683 | 402,127 | 1,133,267 | 12,465,937 |
| -1 | -11 | -31 | -139 | -263 | -341 | -1,529 | -2,893 | -4,309 | -8,153 | -36,557 | -47,399 | -89,683 | -402,127 | -1,133,267 | -12,465,937 |
