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 122,524,051, 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 | 122,524,051 | |
| -1 | -122,524,051 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,524,051.
Example:
1 x 122,524,051 = 122,524,051
and
-1 x -122,524,051 = 122,524,051
Notice both answers equal 122,524,051
With that explanation out of the way, let's continue. Next, we take the number 122,524,051 and divide it by 2:
122,524,051 ÷ 2 = 61,262,025.5
If the quotient is a whole number, then 2 and 61,262,025.5 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 | 122,524,051 | |
| -1 | -122,524,051 |
Now, we try dividing 122,524,051 by 3:
122,524,051 ÷ 3 = 40,841,350.3333
If the quotient is a whole number, then 3 and 40,841,350.3333 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 | 122,524,051 | |
| -1 | -122,524,051 |
Let's try dividing by 4:
122,524,051 ÷ 4 = 30,631,012.75
If the quotient is a whole number, then 4 and 30,631,012.75 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 | 122,524,051 | |
| -1 | 122,524,051 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 367 | 421 | 793 | 4,771 | 5,473 | 22,387 | 25,681 | 154,507 | 291,031 | 333,853 | 2,008,591 | 9,424,927 | 122,524,051 |
| -1 | -13 | -61 | -367 | -421 | -793 | -4,771 | -5,473 | -22,387 | -25,681 | -154,507 | -291,031 | -333,853 | -2,008,591 | -9,424,927 | -122,524,051 |
