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 19,893,463, 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 | 19,893,463 | |
-1 | -19,893,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,893,463.
Example:
1 x 19,893,463 = 19,893,463
and
-1 x -19,893,463 = 19,893,463
Notice both answers equal 19,893,463
With that explanation out of the way, let's continue. Next, we take the number 19,893,463 and divide it by 2:
19,893,463 ÷ 2 = 9,946,731.5
If the quotient is a whole number, then 2 and 9,946,731.5 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 | 19,893,463 | |
-1 | -19,893,463 |
Now, we try dividing 19,893,463 by 3:
19,893,463 ÷ 3 = 6,631,154.3333
If the quotient is a whole number, then 3 and 6,631,154.3333 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 | 19,893,463 | |
-1 | -19,893,463 |
Let's try dividing by 4:
19,893,463 ÷ 4 = 4,973,365.75
If the quotient is a whole number, then 4 and 4,973,365.75 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 | 19,893,463 | |
-1 | 19,893,463 |
If you did it right, you will end up with this table:
1 | 487 | 40,849 | 19,893,463 |
-1 | -487 | -40,849 | -19,893,463 |
