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 271,155,319, 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 | 271,155,319 | |
-1 | -271,155,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,155,319.
Example:
1 x 271,155,319 = 271,155,319
and
-1 x -271,155,319 = 271,155,319
Notice both answers equal 271,155,319
With that explanation out of the way, let's continue. Next, we take the number 271,155,319 and divide it by 2:
271,155,319 ÷ 2 = 135,577,659.5
If the quotient is a whole number, then 2 and 135,577,659.5 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 | 271,155,319 | |
-1 | -271,155,319 |
Now, we try dividing 271,155,319 by 3:
271,155,319 ÷ 3 = 90,385,106.3333
If the quotient is a whole number, then 3 and 90,385,106.3333 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 | 271,155,319 | |
-1 | -271,155,319 |
Let's try dividing by 4:
271,155,319 ÷ 4 = 67,788,829.75
If the quotient is a whole number, then 4 and 67,788,829.75 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 | 271,155,319 | |
-1 | 271,155,319 |
If you did it right, you will end up with this table:
1 | 71 | 3,819,089 | 271,155,319 |
-1 | -71 | -3,819,089 | -271,155,319 |
