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 9,436,861, 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 | 9,436,861 | |
| -1 | -9,436,861 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,436,861.
Example:
1 x 9,436,861 = 9,436,861
and
-1 x -9,436,861 = 9,436,861
Notice both answers equal 9,436,861
With that explanation out of the way, let's continue. Next, we take the number 9,436,861 and divide it by 2:
9,436,861 ÷ 2 = 4,718,430.5
If the quotient is a whole number, then 2 and 4,718,430.5 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 | 9,436,861 | |
| -1 | -9,436,861 |
Now, we try dividing 9,436,861 by 3:
9,436,861 ÷ 3 = 3,145,620.3333
If the quotient is a whole number, then 3 and 3,145,620.3333 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 | 9,436,861 | |
| -1 | -9,436,861 |
Let's try dividing by 4:
9,436,861 ÷ 4 = 2,359,215.25
If the quotient is a whole number, then 4 and 2,359,215.25 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 | 9,436,861 | |
| -1 | 9,436,861 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 203 | 229 | 841 | 1,421 | 1,603 | 5,887 | 6,641 | 11,221 | 41,209 | 46,487 | 192,589 | 325,409 | 1,348,123 | 9,436,861 |
| -1 | -7 | -29 | -49 | -203 | -229 | -841 | -1,421 | -1,603 | -5,887 | -6,641 | -11,221 | -41,209 | -46,487 | -192,589 | -325,409 | -1,348,123 | -9,436,861 |
