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 108,765,563, 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 | 108,765,563 | |
-1 | -108,765,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,765,563.
Example:
1 x 108,765,563 = 108,765,563
and
-1 x -108,765,563 = 108,765,563
Notice both answers equal 108,765,563
With that explanation out of the way, let's continue. Next, we take the number 108,765,563 and divide it by 2:
108,765,563 ÷ 2 = 54,382,781.5
If the quotient is a whole number, then 2 and 54,382,781.5 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 | 108,765,563 | |
-1 | -108,765,563 |
Now, we try dividing 108,765,563 by 3:
108,765,563 ÷ 3 = 36,255,187.6667
If the quotient is a whole number, then 3 and 36,255,187.6667 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 | 108,765,563 | |
-1 | -108,765,563 |
Let's try dividing by 4:
108,765,563 ÷ 4 = 27,191,390.75
If the quotient is a whole number, then 4 and 27,191,390.75 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 | 108,765,563 | |
-1 | 108,765,563 |
If you did it right, you will end up with this table:
1 | 709 | 153,407 | 108,765,563 |
-1 | -709 | -153,407 | -108,765,563 |
