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 115,445,227, 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 | 115,445,227 | |
-1 | -115,445,227 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,445,227.
Example:
1 x 115,445,227 = 115,445,227
and
-1 x -115,445,227 = 115,445,227
Notice both answers equal 115,445,227
With that explanation out of the way, let's continue. Next, we take the number 115,445,227 and divide it by 2:
115,445,227 ÷ 2 = 57,722,613.5
If the quotient is a whole number, then 2 and 57,722,613.5 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 | 115,445,227 | |
-1 | -115,445,227 |
Now, we try dividing 115,445,227 by 3:
115,445,227 ÷ 3 = 38,481,742.3333
If the quotient is a whole number, then 3 and 38,481,742.3333 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 | 115,445,227 | |
-1 | -115,445,227 |
Let's try dividing by 4:
115,445,227 ÷ 4 = 28,861,306.75
If the quotient is a whole number, then 4 and 28,861,306.75 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 | 115,445,227 | |
-1 | 115,445,227 |
If you did it right, you will end up with this table:
1 | 479 | 241,013 | 115,445,227 |
-1 | -479 | -241,013 | -115,445,227 |
