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 123,134,011, 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 | 123,134,011 | |
| -1 | -123,134,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,134,011.
Example:
1 x 123,134,011 = 123,134,011
and
-1 x -123,134,011 = 123,134,011
Notice both answers equal 123,134,011
With that explanation out of the way, let's continue. Next, we take the number 123,134,011 and divide it by 2:
123,134,011 ÷ 2 = 61,567,005.5
If the quotient is a whole number, then 2 and 61,567,005.5 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 | 123,134,011 | |
| -1 | -123,134,011 |
Now, we try dividing 123,134,011 by 3:
123,134,011 ÷ 3 = 41,044,670.3333
If the quotient is a whole number, then 3 and 41,044,670.3333 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 | 123,134,011 | |
| -1 | -123,134,011 |
Let's try dividing by 4:
123,134,011 ÷ 4 = 30,783,502.75
If the quotient is a whole number, then 4 and 30,783,502.75 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 | 123,134,011 | |
| -1 | 123,134,011 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 539 | 637 | 1,001 | 7,007 | 17,573 | 123,011 | 193,303 | 228,449 | 861,077 | 1,353,121 | 1,599,143 | 2,512,939 | 9,471,847 | 11,194,001 | 17,590,573 | 123,134,011 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -539 | -637 | -1,001 | -7,007 | -17,573 | -123,011 | -193,303 | -228,449 | -861,077 | -1,353,121 | -1,599,143 | -2,512,939 | -9,471,847 | -11,194,001 | -17,590,573 | -123,134,011 |
