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 10,427,207, 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 | 10,427,207 | |
| -1 | -10,427,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,427,207.
Example:
1 x 10,427,207 = 10,427,207
and
-1 x -10,427,207 = 10,427,207
Notice both answers equal 10,427,207
With that explanation out of the way, let's continue. Next, we take the number 10,427,207 and divide it by 2:
10,427,207 ÷ 2 = 5,213,603.5
If the quotient is a whole number, then 2 and 5,213,603.5 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 | 10,427,207 | |
| -1 | -10,427,207 |
Now, we try dividing 10,427,207 by 3:
10,427,207 ÷ 3 = 3,475,735.6667
If the quotient is a whole number, then 3 and 3,475,735.6667 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 | 10,427,207 | |
| -1 | -10,427,207 |
Let's try dividing by 4:
10,427,207 ÷ 4 = 2,606,801.75
If the quotient is a whole number, then 4 and 2,606,801.75 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 | 10,427,207 | |
| -1 | 10,427,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 83 | 131 | 137 | 581 | 917 | 959 | 10,873 | 11,371 | 17,947 | 76,111 | 79,597 | 125,629 | 1,489,601 | 10,427,207 |
| -1 | -7 | -83 | -131 | -137 | -581 | -917 | -959 | -10,873 | -11,371 | -17,947 | -76,111 | -79,597 | -125,629 | -1,489,601 | -10,427,207 |
