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 121,012,463, 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 | 121,012,463 | |
| -1 | -121,012,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,012,463.
Example:
1 x 121,012,463 = 121,012,463
and
-1 x -121,012,463 = 121,012,463
Notice both answers equal 121,012,463
With that explanation out of the way, let's continue. Next, we take the number 121,012,463 and divide it by 2:
121,012,463 ÷ 2 = 60,506,231.5
If the quotient is a whole number, then 2 and 60,506,231.5 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 | 121,012,463 | |
| -1 | -121,012,463 |
Now, we try dividing 121,012,463 by 3:
121,012,463 ÷ 3 = 40,337,487.6667
If the quotient is a whole number, then 3 and 40,337,487.6667 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 | 121,012,463 | |
| -1 | -121,012,463 |
Let's try dividing by 4:
121,012,463 ÷ 4 = 30,253,115.75
If the quotient is a whole number, then 4 and 30,253,115.75 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 | 121,012,463 | |
| -1 | 121,012,463 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 121 | 143 | 209 | 247 | 1,573 | 2,299 | 2,717 | 4,049 | 29,887 | 44,539 | 52,637 | 76,931 | 489,929 | 579,007 | 846,241 | 1,000,103 | 6,369,077 | 9,308,651 | 11,001,133 | 121,012,463 |
| -1 | -11 | -13 | -19 | -121 | -143 | -209 | -247 | -1,573 | -2,299 | -2,717 | -4,049 | -29,887 | -44,539 | -52,637 | -76,931 | -489,929 | -579,007 | -846,241 | -1,000,103 | -6,369,077 | -9,308,651 | -11,001,133 | -121,012,463 |
