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 20,114,347, 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 | 20,114,347 | |
| -1 | -20,114,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,114,347.
Example:
1 x 20,114,347 = 20,114,347
and
-1 x -20,114,347 = 20,114,347
Notice both answers equal 20,114,347
With that explanation out of the way, let's continue. Next, we take the number 20,114,347 and divide it by 2:
20,114,347 ÷ 2 = 10,057,173.5
If the quotient is a whole number, then 2 and 10,057,173.5 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 | 20,114,347 | |
| -1 | -20,114,347 |
Now, we try dividing 20,114,347 by 3:
20,114,347 ÷ 3 = 6,704,782.3333
If the quotient is a whole number, then 3 and 6,704,782.3333 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 | 20,114,347 | |
| -1 | -20,114,347 |
Let's try dividing by 4:
20,114,347 ÷ 4 = 5,028,586.75
If the quotient is a whole number, then 4 and 5,028,586.75 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 | 20,114,347 | |
| -1 | 20,114,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 73 | 407 | 677 | 803 | 2,701 | 7,447 | 25,049 | 29,711 | 49,421 | 275,539 | 543,631 | 1,828,577 | 20,114,347 |
| -1 | -11 | -37 | -73 | -407 | -677 | -803 | -2,701 | -7,447 | -25,049 | -29,711 | -49,421 | -275,539 | -543,631 | -1,828,577 | -20,114,347 |
