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 12,107,275, 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 | 12,107,275 | |
| -1 | -12,107,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,107,275.
Example:
1 x 12,107,275 = 12,107,275
and
-1 x -12,107,275 = 12,107,275
Notice both answers equal 12,107,275
With that explanation out of the way, let's continue. Next, we take the number 12,107,275 and divide it by 2:
12,107,275 ÷ 2 = 6,053,637.5
If the quotient is a whole number, then 2 and 6,053,637.5 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 | 12,107,275 | |
| -1 | -12,107,275 |
Now, we try dividing 12,107,275 by 3:
12,107,275 ÷ 3 = 4,035,758.3333
If the quotient is a whole number, then 3 and 4,035,758.3333 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 | 12,107,275 | |
| -1 | -12,107,275 |
Let's try dividing by 4:
12,107,275 ÷ 4 = 3,026,818.75
If the quotient is a whole number, then 4 and 3,026,818.75 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 | 12,107,275 | |
| -1 | 12,107,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 71 | 95 | 355 | 359 | 475 | 1,349 | 1,775 | 1,795 | 6,745 | 6,821 | 8,975 | 25,489 | 33,725 | 34,105 | 127,445 | 170,525 | 484,291 | 637,225 | 2,421,455 | 12,107,275 |
| -1 | -5 | -19 | -25 | -71 | -95 | -355 | -359 | -475 | -1,349 | -1,775 | -1,795 | -6,745 | -6,821 | -8,975 | -25,489 | -33,725 | -34,105 | -127,445 | -170,525 | -484,291 | -637,225 | -2,421,455 | -12,107,275 |
