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 20,924,795, 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 | 20,924,795 | |
| -1 | -20,924,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,924,795.
Example:
1 x 20,924,795 = 20,924,795
and
-1 x -20,924,795 = 20,924,795
Notice both answers equal 20,924,795
With that explanation out of the way, let's continue. Next, we take the number 20,924,795 and divide it by 2:
20,924,795 ÷ 2 = 10,462,397.5
If the quotient is a whole number, then 2 and 10,462,397.5 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 | 20,924,795 | |
| -1 | -20,924,795 |
Now, we try dividing 20,924,795 by 3:
20,924,795 ÷ 3 = 6,974,931.6667
If the quotient is a whole number, then 3 and 6,974,931.6667 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 | 20,924,795 | |
| -1 | -20,924,795 |
Let's try dividing by 4:
20,924,795 ÷ 4 = 5,231,198.75
If the quotient is a whole number, then 4 and 5,231,198.75 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 | 20,924,795 | |
| -1 | 20,924,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 5,953 | 29,765 | 113,107 | 220,261 | 565,535 | 1,101,305 | 4,184,959 | 20,924,795 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -5,953 | -29,765 | -113,107 | -220,261 | -565,535 | -1,101,305 | -4,184,959 | -20,924,795 |
