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 123,766,693, 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 | 123,766,693 | |
| -1 | -123,766,693 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,766,693.
Example:
1 x 123,766,693 = 123,766,693
and
-1 x -123,766,693 = 123,766,693
Notice both answers equal 123,766,693
With that explanation out of the way, let's continue. Next, we take the number 123,766,693 and divide it by 2:
123,766,693 ÷ 2 = 61,883,346.5
If the quotient is a whole number, then 2 and 61,883,346.5 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 | 123,766,693 | |
| -1 | -123,766,693 |
Now, we try dividing 123,766,693 by 3:
123,766,693 ÷ 3 = 41,255,564.3333
If the quotient is a whole number, then 3 and 41,255,564.3333 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 | 123,766,693 | |
| -1 | -123,766,693 |
Let's try dividing by 4:
123,766,693 ÷ 4 = 30,941,673.25
If the quotient is a whole number, then 4 and 30,941,673.25 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 | 123,766,693 | |
| -1 | 123,766,693 |
If you did it right, you will end up with this table:
| 1 | 29 | 79 | 89 | 607 | 2,291 | 2,581 | 7,031 | 17,603 | 47,953 | 54,023 | 203,899 | 1,390,637 | 1,566,667 | 4,267,817 | 123,766,693 |
| -1 | -29 | -79 | -89 | -607 | -2,291 | -2,581 | -7,031 | -17,603 | -47,953 | -54,023 | -203,899 | -1,390,637 | -1,566,667 | -4,267,817 | -123,766,693 |
