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 134,050,315, 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 | 134,050,315 | |
| -1 | -134,050,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,050,315.
Example:
1 x 134,050,315 = 134,050,315
and
-1 x -134,050,315 = 134,050,315
Notice both answers equal 134,050,315
With that explanation out of the way, let's continue. Next, we take the number 134,050,315 and divide it by 2:
134,050,315 ÷ 2 = 67,025,157.5
If the quotient is a whole number, then 2 and 67,025,157.5 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 | 134,050,315 | |
| -1 | -134,050,315 |
Now, we try dividing 134,050,315 by 3:
134,050,315 ÷ 3 = 44,683,438.3333
If the quotient is a whole number, then 3 and 44,683,438.3333 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 | 134,050,315 | |
| -1 | -134,050,315 |
Let's try dividing by 4:
134,050,315 ÷ 4 = 33,512,578.75
If the quotient is a whole number, then 4 and 33,512,578.75 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 | 134,050,315 | |
| -1 | 134,050,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 251 | 1,255 | 1,757 | 8,785 | 15,259 | 76,295 | 106,813 | 534,065 | 3,830,009 | 19,150,045 | 26,810,063 | 134,050,315 |
| -1 | -5 | -7 | -35 | -251 | -1,255 | -1,757 | -8,785 | -15,259 | -76,295 | -106,813 | -534,065 | -3,830,009 | -19,150,045 | -26,810,063 | -134,050,315 |
