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 447,643,657, 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 | 447,643,657 | |
-1 | -447,643,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 447,643,657.
Example:
1 x 447,643,657 = 447,643,657
and
-1 x -447,643,657 = 447,643,657
Notice both answers equal 447,643,657
With that explanation out of the way, let's continue. Next, we take the number 447,643,657 and divide it by 2:
447,643,657 ÷ 2 = 223,821,828.5
If the quotient is a whole number, then 2 and 223,821,828.5 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 | 447,643,657 | |
-1 | -447,643,657 |
Now, we try dividing 447,643,657 by 3:
447,643,657 ÷ 3 = 149,214,552.3333
If the quotient is a whole number, then 3 and 149,214,552.3333 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 | 447,643,657 | |
-1 | -447,643,657 |
Let's try dividing by 4:
447,643,657 ÷ 4 = 111,910,914.25
If the quotient is a whole number, then 4 and 111,910,914.25 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 | 447,643,657 | |
-1 | 447,643,657 |
If you did it right, you will end up with this table:
1 | 1,451 | 308,507 | 447,643,657 |
-1 | -1,451 | -308,507 | -447,643,657 |
