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 19,567,723, 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 | 19,567,723 | |
| -1 | -19,567,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,567,723.
Example:
1 x 19,567,723 = 19,567,723
and
-1 x -19,567,723 = 19,567,723
Notice both answers equal 19,567,723
With that explanation out of the way, let's continue. Next, we take the number 19,567,723 and divide it by 2:
19,567,723 ÷ 2 = 9,783,861.5
If the quotient is a whole number, then 2 and 9,783,861.5 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 | 19,567,723 | |
| -1 | -19,567,723 |
Now, we try dividing 19,567,723 by 3:
19,567,723 ÷ 3 = 6,522,574.3333
If the quotient is a whole number, then 3 and 6,522,574.3333 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 | 19,567,723 | |
| -1 | -19,567,723 |
Let's try dividing by 4:
19,567,723 ÷ 4 = 4,891,930.75
If the quotient is a whole number, then 4 and 4,891,930.75 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 | 19,567,723 | |
| -1 | 19,567,723 |
If you did it right, you will end up with this table:
| 1 | 7 | 73 | 149 | 257 | 511 | 1,043 | 1,799 | 10,877 | 18,761 | 38,293 | 76,139 | 131,327 | 268,051 | 2,795,389 | 19,567,723 |
| -1 | -7 | -73 | -149 | -257 | -511 | -1,043 | -1,799 | -10,877 | -18,761 | -38,293 | -76,139 | -131,327 | -268,051 | -2,795,389 | -19,567,723 |
