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 634,997, 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 | 634,997 | |
-1 | -634,997 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 634,997.
Example:
1 x 634,997 = 634,997
and
-1 x -634,997 = 634,997
Notice both answers equal 634,997
With that explanation out of the way, let's continue. Next, we take the number 634,997 and divide it by 2:
634,997 ÷ 2 = 317,498.5
If the quotient is a whole number, then 2 and 317,498.5 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 | 634,997 | |
-1 | -634,997 |
Now, we try dividing 634,997 by 3:
634,997 ÷ 3 = 211,665.6667
If the quotient is a whole number, then 3 and 211,665.6667 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 | 634,997 | |
-1 | -634,997 |
Let's try dividing by 4:
634,997 ÷ 4 = 158,749.25
If the quotient is a whole number, then 4 and 158,749.25 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 | 634,997 | |
-1 | 634,997 |
If you did it right, you will end up with this table:
1 | 11 | 57,727 | 634,997 |
-1 | -11 | -57,727 | -634,997 |
