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 12,375,517, 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 | 12,375,517 | |
| -1 | -12,375,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,375,517.
Example:
1 x 12,375,517 = 12,375,517
and
-1 x -12,375,517 = 12,375,517
Notice both answers equal 12,375,517
With that explanation out of the way, let's continue. Next, we take the number 12,375,517 and divide it by 2:
12,375,517 ÷ 2 = 6,187,758.5
If the quotient is a whole number, then 2 and 6,187,758.5 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 | 12,375,517 | |
| -1 | -12,375,517 |
Now, we try dividing 12,375,517 by 3:
12,375,517 ÷ 3 = 4,125,172.3333
If the quotient is a whole number, then 3 and 4,125,172.3333 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 | 12,375,517 | |
| -1 | -12,375,517 |
Let's try dividing by 4:
12,375,517 ÷ 4 = 3,093,879.25
If the quotient is a whole number, then 4 and 3,093,879.25 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 | 12,375,517 | |
| -1 | 12,375,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 19 | 77 | 121 | 133 | 209 | 769 | 847 | 1,463 | 2,299 | 5,383 | 8,459 | 14,611 | 16,093 | 59,213 | 93,049 | 102,277 | 160,721 | 651,343 | 1,125,047 | 1,767,931 | 12,375,517 |
| -1 | -7 | -11 | -19 | -77 | -121 | -133 | -209 | -769 | -847 | -1,463 | -2,299 | -5,383 | -8,459 | -14,611 | -16,093 | -59,213 | -93,049 | -102,277 | -160,721 | -651,343 | -1,125,047 | -1,767,931 | -12,375,517 |
