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 19,622,611, 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 | 19,622,611 | |
| -1 | -19,622,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,622,611.
Example:
1 x 19,622,611 = 19,622,611
and
-1 x -19,622,611 = 19,622,611
Notice both answers equal 19,622,611
With that explanation out of the way, let's continue. Next, we take the number 19,622,611 and divide it by 2:
19,622,611 ÷ 2 = 9,811,305.5
If the quotient is a whole number, then 2 and 9,811,305.5 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 | 19,622,611 | |
| -1 | -19,622,611 |
Now, we try dividing 19,622,611 by 3:
19,622,611 ÷ 3 = 6,540,870.3333
If the quotient is a whole number, then 3 and 6,540,870.3333 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 | 19,622,611 | |
| -1 | -19,622,611 |
Let's try dividing by 4:
19,622,611 ÷ 4 = 4,905,652.75
If the quotient is a whole number, then 4 and 4,905,652.75 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 | 19,622,611 | |
| -1 | 19,622,611 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 83 | 437 | 541 | 1,577 | 1,909 | 10,279 | 12,443 | 36,271 | 44,903 | 236,417 | 853,157 | 1,032,769 | 19,622,611 |
| -1 | -19 | -23 | -83 | -437 | -541 | -1,577 | -1,909 | -10,279 | -12,443 | -36,271 | -44,903 | -236,417 | -853,157 | -1,032,769 | -19,622,611 |
