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 243,703,027, 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 | 243,703,027 | |
-1 | -243,703,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,703,027.
Example:
1 x 243,703,027 = 243,703,027
and
-1 x -243,703,027 = 243,703,027
Notice both answers equal 243,703,027
With that explanation out of the way, let's continue. Next, we take the number 243,703,027 and divide it by 2:
243,703,027 ÷ 2 = 121,851,513.5
If the quotient is a whole number, then 2 and 121,851,513.5 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 | 243,703,027 | |
-1 | -243,703,027 |
Now, we try dividing 243,703,027 by 3:
243,703,027 ÷ 3 = 81,234,342.3333
If the quotient is a whole number, then 3 and 81,234,342.3333 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 | 243,703,027 | |
-1 | -243,703,027 |
Let's try dividing by 4:
243,703,027 ÷ 4 = 60,925,756.75
If the quotient is a whole number, then 4 and 60,925,756.75 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 | 243,703,027 | |
-1 | 243,703,027 |
If you did it right, you will end up with this table:
1 | 71 | 3,432,437 | 243,703,027 |
-1 | -71 | -3,432,437 | -243,703,027 |
