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 12,077,923, 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 | 12,077,923 | |
| -1 | -12,077,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,077,923.
Example:
1 x 12,077,923 = 12,077,923
and
-1 x -12,077,923 = 12,077,923
Notice both answers equal 12,077,923
With that explanation out of the way, let's continue. Next, we take the number 12,077,923 and divide it by 2:
12,077,923 ÷ 2 = 6,038,961.5
If the quotient is a whole number, then 2 and 6,038,961.5 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 | 12,077,923 | |
| -1 | -12,077,923 |
Now, we try dividing 12,077,923 by 3:
12,077,923 ÷ 3 = 4,025,974.3333
If the quotient is a whole number, then 3 and 4,025,974.3333 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 | 12,077,923 | |
| -1 | -12,077,923 |
Let's try dividing by 4:
12,077,923 ÷ 4 = 3,019,480.75
If the quotient is a whole number, then 4 and 3,019,480.75 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 | 12,077,923 | |
| -1 | 12,077,923 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 89 | 143 | 169 | 803 | 949 | 979 | 1,157 | 1,859 | 6,497 | 10,439 | 12,337 | 12,727 | 15,041 | 71,467 | 84,461 | 135,707 | 165,451 | 929,071 | 1,097,993 | 12,077,923 |
| -1 | -11 | -13 | -73 | -89 | -143 | -169 | -803 | -949 | -979 | -1,157 | -1,859 | -6,497 | -10,439 | -12,337 | -12,727 | -15,041 | -71,467 | -84,461 | -135,707 | -165,451 | -929,071 | -1,097,993 | -12,077,923 |
