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 122,341,649, 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 | 122,341,649 | |
| -1 | -122,341,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,341,649.
Example:
1 x 122,341,649 = 122,341,649
and
-1 x -122,341,649 = 122,341,649
Notice both answers equal 122,341,649
With that explanation out of the way, let's continue. Next, we take the number 122,341,649 and divide it by 2:
122,341,649 ÷ 2 = 61,170,824.5
If the quotient is a whole number, then 2 and 61,170,824.5 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 | 122,341,649 | |
| -1 | -122,341,649 |
Now, we try dividing 122,341,649 by 3:
122,341,649 ÷ 3 = 40,780,549.6667
If the quotient is a whole number, then 3 and 40,780,549.6667 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 | 122,341,649 | |
| -1 | -122,341,649 |
Let's try dividing by 4:
122,341,649 ÷ 4 = 30,585,412.25
If the quotient is a whole number, then 4 and 30,585,412.25 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 | 122,341,649 | |
| -1 | 122,341,649 |
If you did it right, you will end up with this table:
| 1 | 53 | 73 | 103 | 307 | 3,869 | 5,459 | 7,519 | 16,271 | 22,411 | 31,621 | 398,507 | 1,187,783 | 1,675,913 | 2,308,333 | 122,341,649 |
| -1 | -53 | -73 | -103 | -307 | -3,869 | -5,459 | -7,519 | -16,271 | -22,411 | -31,621 | -398,507 | -1,187,783 | -1,675,913 | -2,308,333 | -122,341,649 |
