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 271,226,137, 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 | 271,226,137 | |
| -1 | -271,226,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,226,137.
Example:
1 x 271,226,137 = 271,226,137
and
-1 x -271,226,137 = 271,226,137
Notice both answers equal 271,226,137
With that explanation out of the way, let's continue. Next, we take the number 271,226,137 and divide it by 2:
271,226,137 ÷ 2 = 135,613,068.5
If the quotient is a whole number, then 2 and 135,613,068.5 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 | 271,226,137 | |
| -1 | -271,226,137 |
Now, we try dividing 271,226,137 by 3:
271,226,137 ÷ 3 = 90,408,712.3333
If the quotient is a whole number, then 3 and 90,408,712.3333 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 | 271,226,137 | |
| -1 | -271,226,137 |
Let's try dividing by 4:
271,226,137 ÷ 4 = 67,806,534.25
If the quotient is a whole number, then 4 and 67,806,534.25 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 | 271,226,137 | |
| -1 | 271,226,137 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 557 | 3,899 | 5,351 | 7,241 | 37,457 | 50,687 | 69,563 | 486,941 | 2,980,507 | 20,863,549 | 38,746,591 | 271,226,137 |
| -1 | -7 | -13 | -91 | -557 | -3,899 | -5,351 | -7,241 | -37,457 | -50,687 | -69,563 | -486,941 | -2,980,507 | -20,863,549 | -38,746,591 | -271,226,137 |
