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 89,713,021, 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 | 89,713,021 | |
-1 | -89,713,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 89,713,021.
Example:
1 x 89,713,021 = 89,713,021
and
-1 x -89,713,021 = 89,713,021
Notice both answers equal 89,713,021
With that explanation out of the way, let's continue. Next, we take the number 89,713,021 and divide it by 2:
89,713,021 ÷ 2 = 44,856,510.5
If the quotient is a whole number, then 2 and 44,856,510.5 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 | 89,713,021 | |
-1 | -89,713,021 |
Now, we try dividing 89,713,021 by 3:
89,713,021 ÷ 3 = 29,904,340.3333
If the quotient is a whole number, then 3 and 29,904,340.3333 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 | 89,713,021 | |
-1 | -89,713,021 |
Let's try dividing by 4:
89,713,021 ÷ 4 = 22,428,255.25
If the quotient is a whole number, then 4 and 22,428,255.25 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 | 89,713,021 | |
-1 | 89,713,021 |
If you did it right, you will end up with this table:
1 | 2,473 | 36,277 | 89,713,021 |
-1 | -2,473 | -36,277 | -89,713,021 |
