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 134,030,225, 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 | 134,030,225 | |
| -1 | -134,030,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,030,225.
Example:
1 x 134,030,225 = 134,030,225
and
-1 x -134,030,225 = 134,030,225
Notice both answers equal 134,030,225
With that explanation out of the way, let's continue. Next, we take the number 134,030,225 and divide it by 2:
134,030,225 ÷ 2 = 67,015,112.5
If the quotient is a whole number, then 2 and 67,015,112.5 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 | 134,030,225 | |
| -1 | -134,030,225 |
Now, we try dividing 134,030,225 by 3:
134,030,225 ÷ 3 = 44,676,741.6667
If the quotient is a whole number, then 3 and 44,676,741.6667 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 | 134,030,225 | |
| -1 | -134,030,225 |
Let's try dividing by 4:
134,030,225 ÷ 4 = 33,507,556.25
If the quotient is a whole number, then 4 and 33,507,556.25 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 | 134,030,225 | |
| -1 | 134,030,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 431 | 1,777 | 2,155 | 3,017 | 8,885 | 10,775 | 12,439 | 15,085 | 44,425 | 62,195 | 75,425 | 310,975 | 765,887 | 3,829,435 | 5,361,209 | 19,147,175 | 26,806,045 | 134,030,225 |
| -1 | -5 | -7 | -25 | -35 | -175 | -431 | -1,777 | -2,155 | -3,017 | -8,885 | -10,775 | -12,439 | -15,085 | -44,425 | -62,195 | -75,425 | -310,975 | -765,887 | -3,829,435 | -5,361,209 | -19,147,175 | -26,806,045 | -134,030,225 |
