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 864,145,033, 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 | 864,145,033 | |
-1 | -864,145,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 864,145,033.
Example:
1 x 864,145,033 = 864,145,033
and
-1 x -864,145,033 = 864,145,033
Notice both answers equal 864,145,033
With that explanation out of the way, let's continue. Next, we take the number 864,145,033 and divide it by 2:
864,145,033 ÷ 2 = 432,072,516.5
If the quotient is a whole number, then 2 and 432,072,516.5 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 | 864,145,033 | |
-1 | -864,145,033 |
Now, we try dividing 864,145,033 by 3:
864,145,033 ÷ 3 = 288,048,344.3333
If the quotient is a whole number, then 3 and 288,048,344.3333 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 | 864,145,033 | |
-1 | -864,145,033 |
Let's try dividing by 4:
864,145,033 ÷ 4 = 216,036,258.25
If the quotient is a whole number, then 4 and 216,036,258.25 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 | 864,145,033 | |
-1 | 864,145,033 |
If you did it right, you will end up with this table:
1 | 10,141 | 85,213 | 864,145,033 |
-1 | -10,141 | -85,213 | -864,145,033 |
