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 130,765,075, 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 | 130,765,075 | |
| -1 | -130,765,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,765,075.
Example:
1 x 130,765,075 = 130,765,075
and
-1 x -130,765,075 = 130,765,075
Notice both answers equal 130,765,075
With that explanation out of the way, let's continue. Next, we take the number 130,765,075 and divide it by 2:
130,765,075 ÷ 2 = 65,382,537.5
If the quotient is a whole number, then 2 and 65,382,537.5 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 | 130,765,075 | |
| -1 | -130,765,075 |
Now, we try dividing 130,765,075 by 3:
130,765,075 ÷ 3 = 43,588,358.3333
If the quotient is a whole number, then 3 and 43,588,358.3333 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 | 130,765,075 | |
| -1 | -130,765,075 |
Let's try dividing by 4:
130,765,075 ÷ 4 = 32,691,268.75
If the quotient is a whole number, then 4 and 32,691,268.75 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 | 130,765,075 | |
| -1 | 130,765,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 106,747 | 533,735 | 747,229 | 2,668,675 | 3,736,145 | 5,230,603 | 18,680,725 | 26,153,015 | 130,765,075 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -106,747 | -533,735 | -747,229 | -2,668,675 | -3,736,145 | -5,230,603 | -18,680,725 | -26,153,015 | -130,765,075 |
