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 8,938,447, 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 | 8,938,447 | |
| -1 | -8,938,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,938,447.
Example:
1 x 8,938,447 = 8,938,447
and
-1 x -8,938,447 = 8,938,447
Notice both answers equal 8,938,447
With that explanation out of the way, let's continue. Next, we take the number 8,938,447 and divide it by 2:
8,938,447 ÷ 2 = 4,469,223.5
If the quotient is a whole number, then 2 and 4,469,223.5 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 | 8,938,447 | |
| -1 | -8,938,447 |
Now, we try dividing 8,938,447 by 3:
8,938,447 ÷ 3 = 2,979,482.3333
If the quotient is a whole number, then 3 and 2,979,482.3333 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 | 8,938,447 | |
| -1 | -8,938,447 |
Let's try dividing by 4:
8,938,447 ÷ 4 = 2,234,611.75
If the quotient is a whole number, then 4 and 2,234,611.75 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 | 8,938,447 | |
| -1 | 8,938,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 31 | 119 | 217 | 527 | 2,423 | 3,689 | 16,961 | 41,191 | 75,113 | 288,337 | 525,791 | 1,276,921 | 8,938,447 |
| -1 | -7 | -17 | -31 | -119 | -217 | -527 | -2,423 | -3,689 | -16,961 | -41,191 | -75,113 | -288,337 | -525,791 | -1,276,921 | -8,938,447 |
