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 636,095, 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 | 636,095 | |
-1 | -636,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 636,095.
Example:
1 x 636,095 = 636,095
and
-1 x -636,095 = 636,095
Notice both answers equal 636,095
With that explanation out of the way, let's continue. Next, we take the number 636,095 and divide it by 2:
636,095 ÷ 2 = 318,047.5
If the quotient is a whole number, then 2 and 318,047.5 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 | 636,095 | |
-1 | -636,095 |
Now, we try dividing 636,095 by 3:
636,095 ÷ 3 = 212,031.6667
If the quotient is a whole number, then 3 and 212,031.6667 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 | 636,095 | |
-1 | -636,095 |
Let's try dividing by 4:
636,095 ÷ 4 = 159,023.75
If the quotient is a whole number, then 4 and 159,023.75 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 | 636,095 | |
-1 | 636,095 |
If you did it right, you will end up with this table:
1 | 5 | 127,219 | 636,095 |
-1 | -5 | -127,219 | -636,095 |
