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 9,871,393, 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 | 9,871,393 | |
| -1 | -9,871,393 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,871,393.
Example:
1 x 9,871,393 = 9,871,393
and
-1 x -9,871,393 = 9,871,393
Notice both answers equal 9,871,393
With that explanation out of the way, let's continue. Next, we take the number 9,871,393 and divide it by 2:
9,871,393 ÷ 2 = 4,935,696.5
If the quotient is a whole number, then 2 and 4,935,696.5 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 | 9,871,393 | |
| -1 | -9,871,393 |
Now, we try dividing 9,871,393 by 3:
9,871,393 ÷ 3 = 3,290,464.3333
If the quotient is a whole number, then 3 and 3,290,464.3333 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 | 9,871,393 | |
| -1 | -9,871,393 |
Let's try dividing by 4:
9,871,393 ÷ 4 = 2,467,848.25
If the quotient is a whole number, then 4 and 2,467,848.25 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 | 9,871,393 | |
| -1 | 9,871,393 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 23 | 49 | 133 | 161 | 437 | 461 | 931 | 1,127 | 3,059 | 3,227 | 8,759 | 10,603 | 21,413 | 22,589 | 61,313 | 74,221 | 201,457 | 429,191 | 519,547 | 1,410,199 | 9,871,393 |
| -1 | -7 | -19 | -23 | -49 | -133 | -161 | -437 | -461 | -931 | -1,127 | -3,059 | -3,227 | -8,759 | -10,603 | -21,413 | -22,589 | -61,313 | -74,221 | -201,457 | -429,191 | -519,547 | -1,410,199 | -9,871,393 |
