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 9,722,951, 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 | 9,722,951 | |
| -1 | -9,722,951 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,722,951.
Example:
1 x 9,722,951 = 9,722,951
and
-1 x -9,722,951 = 9,722,951
Notice both answers equal 9,722,951
With that explanation out of the way, let's continue. Next, we take the number 9,722,951 and divide it by 2:
9,722,951 ÷ 2 = 4,861,475.5
If the quotient is a whole number, then 2 and 4,861,475.5 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 | 9,722,951 | |
| -1 | -9,722,951 |
Now, we try dividing 9,722,951 by 3:
9,722,951 ÷ 3 = 3,240,983.6667
If the quotient is a whole number, then 3 and 3,240,983.6667 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 | 9,722,951 | |
| -1 | -9,722,951 |
Let's try dividing by 4:
9,722,951 ÷ 4 = 2,430,737.75
If the quotient is a whole number, then 4 and 2,430,737.75 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 | 9,722,951 | |
| -1 | 9,722,951 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 131 | 161 | 461 | 917 | 3,013 | 3,227 | 10,603 | 21,091 | 60,391 | 74,221 | 422,737 | 1,388,993 | 9,722,951 |
| -1 | -7 | -23 | -131 | -161 | -461 | -917 | -3,013 | -3,227 | -10,603 | -21,091 | -60,391 | -74,221 | -422,737 | -1,388,993 | -9,722,951 |
