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 36,021,923, 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 | 36,021,923 | |
| -1 | -36,021,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 36,021,923.
Example:
1 x 36,021,923 = 36,021,923
and
-1 x -36,021,923 = 36,021,923
Notice both answers equal 36,021,923
With that explanation out of the way, let's continue. Next, we take the number 36,021,923 and divide it by 2:
36,021,923 ÷ 2 = 18,010,961.5
If the quotient is a whole number, then 2 and 18,010,961.5 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 | 36,021,923 | |
| -1 | -36,021,923 |
Now, we try dividing 36,021,923 by 3:
36,021,923 ÷ 3 = 12,007,307.6667
If the quotient is a whole number, then 3 and 12,007,307.6667 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 | 36,021,923 | |
| -1 | -36,021,923 |
Let's try dividing by 4:
36,021,923 ÷ 4 = 9,005,480.75
If the quotient is a whole number, then 4 and 9,005,480.75 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 | 36,021,923 | |
| -1 | 36,021,923 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 157 | 449 | 511 | 1,099 | 3,143 | 11,461 | 32,777 | 70,493 | 80,227 | 229,439 | 493,451 | 5,145,989 | 36,021,923 |
| -1 | -7 | -73 | -157 | -449 | -511 | -1,099 | -3,143 | -11,461 | -32,777 | -70,493 | -80,227 | -229,439 | -493,451 | -5,145,989 | -36,021,923 |
