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 660,243,523, 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 | 660,243,523 | |
-1 | -660,243,523 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 660,243,523.
Example:
1 x 660,243,523 = 660,243,523
and
-1 x -660,243,523 = 660,243,523
Notice both answers equal 660,243,523
With that explanation out of the way, let's continue. Next, we take the number 660,243,523 and divide it by 2:
660,243,523 ÷ 2 = 330,121,761.5
If the quotient is a whole number, then 2 and 330,121,761.5 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 | 660,243,523 | |
-1 | -660,243,523 |
Now, we try dividing 660,243,523 by 3:
660,243,523 ÷ 3 = 220,081,174.3333
If the quotient is a whole number, then 3 and 220,081,174.3333 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 | 660,243,523 | |
-1 | -660,243,523 |
Let's try dividing by 4:
660,243,523 ÷ 4 = 165,060,880.75
If the quotient is a whole number, then 4 and 165,060,880.75 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 | 660,243,523 | |
-1 | 660,243,523 |
If you did it right, you will end up with this table:
1 | 25,111 | 26,293 | 660,243,523 |
-1 | -25,111 | -26,293 | -660,243,523 |
