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 838,655,473, 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 | 838,655,473 | |
-1 | -838,655,473 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 838,655,473.
Example:
1 x 838,655,473 = 838,655,473
and
-1 x -838,655,473 = 838,655,473
Notice both answers equal 838,655,473
With that explanation out of the way, let's continue. Next, we take the number 838,655,473 and divide it by 2:
838,655,473 ÷ 2 = 419,327,736.5
If the quotient is a whole number, then 2 and 419,327,736.5 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 | 838,655,473 | |
-1 | -838,655,473 |
Now, we try dividing 838,655,473 by 3:
838,655,473 ÷ 3 = 279,551,824.3333
If the quotient is a whole number, then 3 and 279,551,824.3333 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 | 838,655,473 | |
-1 | -838,655,473 |
Let's try dividing by 4:
838,655,473 ÷ 4 = 209,663,868.25
If the quotient is a whole number, then 4 and 209,663,868.25 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 | 838,655,473 | |
-1 | 838,655,473 |
If you did it right, you will end up with this table:
1 | 11,587 | 72,379 | 838,655,473 |
-1 | -11,587 | -72,379 | -838,655,473 |
