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 134,342,551, 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 | 134,342,551 | |
| -1 | -134,342,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,342,551.
Example:
1 x 134,342,551 = 134,342,551
and
-1 x -134,342,551 = 134,342,551
Notice both answers equal 134,342,551
With that explanation out of the way, let's continue. Next, we take the number 134,342,551 and divide it by 2:
134,342,551 ÷ 2 = 67,171,275.5
If the quotient is a whole number, then 2 and 67,171,275.5 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 | 134,342,551 | |
| -1 | -134,342,551 |
Now, we try dividing 134,342,551 by 3:
134,342,551 ÷ 3 = 44,780,850.3333
If the quotient is a whole number, then 3 and 44,780,850.3333 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 | 134,342,551 | |
| -1 | -134,342,551 |
Let's try dividing by 4:
134,342,551 ÷ 4 = 33,585,637.75
If the quotient is a whole number, then 4 and 33,585,637.75 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 | 134,342,551 | |
| -1 | 134,342,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 293 | 2,051 | 3,853 | 4,981 | 26,971 | 34,867 | 65,501 | 458,507 | 1,128,929 | 7,902,503 | 19,191,793 | 134,342,551 |
| -1 | -7 | -17 | -119 | -293 | -2,051 | -3,853 | -4,981 | -26,971 | -34,867 | -65,501 | -458,507 | -1,128,929 | -7,902,503 | -19,191,793 | -134,342,551 |
