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 121,046,375, 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 | 121,046,375 | |
| -1 | -121,046,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,046,375.
Example:
1 x 121,046,375 = 121,046,375
and
-1 x -121,046,375 = 121,046,375
Notice both answers equal 121,046,375
With that explanation out of the way, let's continue. Next, we take the number 121,046,375 and divide it by 2:
121,046,375 ÷ 2 = 60,523,187.5
If the quotient is a whole number, then 2 and 60,523,187.5 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 | 121,046,375 | |
| -1 | -121,046,375 |
Now, we try dividing 121,046,375 by 3:
121,046,375 ÷ 3 = 40,348,791.6667
If the quotient is a whole number, then 3 and 40,348,791.6667 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 | 121,046,375 | |
| -1 | -121,046,375 |
Let's try dividing by 4:
121,046,375 ÷ 4 = 30,261,593.75
If the quotient is a whole number, then 4 and 30,261,593.75 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 | 121,046,375 | |
| -1 | 121,046,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 2,125 | 56,963 | 284,815 | 968,371 | 1,424,075 | 4,841,855 | 7,120,375 | 24,209,275 | 121,046,375 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -2,125 | -56,963 | -284,815 | -968,371 | -1,424,075 | -4,841,855 | -7,120,375 | -24,209,275 | -121,046,375 |
