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 478,163,377, 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 | 478,163,377 | |
-1 | -478,163,377 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,163,377.
Example:
1 x 478,163,377 = 478,163,377
and
-1 x -478,163,377 = 478,163,377
Notice both answers equal 478,163,377
With that explanation out of the way, let's continue. Next, we take the number 478,163,377 and divide it by 2:
478,163,377 ÷ 2 = 239,081,688.5
If the quotient is a whole number, then 2 and 239,081,688.5 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 | 478,163,377 | |
-1 | -478,163,377 |
Now, we try dividing 478,163,377 by 3:
478,163,377 ÷ 3 = 159,387,792.3333
If the quotient is a whole number, then 3 and 159,387,792.3333 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 | 478,163,377 | |
-1 | -478,163,377 |
Let's try dividing by 4:
478,163,377 ÷ 4 = 119,540,844.25
If the quotient is a whole number, then 4 and 119,540,844.25 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 | 478,163,377 | |
-1 | 478,163,377 |
If you did it right, you will end up with this table:
1 | 4,729 | 101,113 | 478,163,377 |
-1 | -4,729 | -101,113 | -478,163,377 |
