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 130,275,863, 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 | 130,275,863 | |
-1 | -130,275,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,275,863.
Example:
1 x 130,275,863 = 130,275,863
and
-1 x -130,275,863 = 130,275,863
Notice both answers equal 130,275,863
With that explanation out of the way, let's continue. Next, we take the number 130,275,863 and divide it by 2:
130,275,863 ÷ 2 = 65,137,931.5
If the quotient is a whole number, then 2 and 65,137,931.5 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 | 130,275,863 | |
-1 | -130,275,863 |
Now, we try dividing 130,275,863 by 3:
130,275,863 ÷ 3 = 43,425,287.6667
If the quotient is a whole number, then 3 and 43,425,287.6667 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 | 130,275,863 | |
-1 | -130,275,863 |
Let's try dividing by 4:
130,275,863 ÷ 4 = 32,568,965.75
If the quotient is a whole number, then 4 and 32,568,965.75 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 | 130,275,863 | |
-1 | 130,275,863 |
If you did it right, you will end up with this table:
1 | 1,087 | 119,849 | 130,275,863 |
-1 | -1,087 | -119,849 | -130,275,863 |
