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 134,234,221, 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 | 134,234,221 | |
| -1 | -134,234,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,234,221.
Example:
1 x 134,234,221 = 134,234,221
and
-1 x -134,234,221 = 134,234,221
Notice both answers equal 134,234,221
With that explanation out of the way, let's continue. Next, we take the number 134,234,221 and divide it by 2:
134,234,221 ÷ 2 = 67,117,110.5
If the quotient is a whole number, then 2 and 67,117,110.5 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 | 134,234,221 | |
| -1 | -134,234,221 |
Now, we try dividing 134,234,221 by 3:
134,234,221 ÷ 3 = 44,744,740.3333
If the quotient is a whole number, then 3 and 44,744,740.3333 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 | 134,234,221 | |
| -1 | -134,234,221 |
Let's try dividing by 4:
134,234,221 ÷ 4 = 33,558,555.25
If the quotient is a whole number, then 4 and 33,558,555.25 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 | 134,234,221 | |
| -1 | 134,234,221 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 209 | 671 | 1,159 | 10,529 | 12,749 | 115,819 | 200,051 | 642,269 | 2,200,561 | 7,064,959 | 12,203,111 | 134,234,221 |
| -1 | -11 | -19 | -61 | -209 | -671 | -1,159 | -10,529 | -12,749 | -115,819 | -200,051 | -642,269 | -2,200,561 | -7,064,959 | -12,203,111 | -134,234,221 |
