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 12,137,095, 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 | 12,137,095 | |
| -1 | -12,137,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,137,095.
Example:
1 x 12,137,095 = 12,137,095
and
-1 x -12,137,095 = 12,137,095
Notice both answers equal 12,137,095
With that explanation out of the way, let's continue. Next, we take the number 12,137,095 and divide it by 2:
12,137,095 ÷ 2 = 6,068,547.5
If the quotient is a whole number, then 2 and 6,068,547.5 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 | 12,137,095 | |
| -1 | -12,137,095 |
Now, we try dividing 12,137,095 by 3:
12,137,095 ÷ 3 = 4,045,698.3333
If the quotient is a whole number, then 3 and 4,045,698.3333 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 | 12,137,095 | |
| -1 | -12,137,095 |
Let's try dividing by 4:
12,137,095 ÷ 4 = 3,034,273.75
If the quotient is a whole number, then 4 and 3,034,273.75 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 | 12,137,095 | |
| -1 | 12,137,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 179 | 191 | 355 | 895 | 955 | 12,709 | 13,561 | 34,189 | 63,545 | 67,805 | 170,945 | 2,427,419 | 12,137,095 |
| -1 | -5 | -71 | -179 | -191 | -355 | -895 | -955 | -12,709 | -13,561 | -34,189 | -63,545 | -67,805 | -170,945 | -2,427,419 | -12,137,095 |
