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 130,150,465, 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 | 130,150,465 | |
| -1 | -130,150,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,150,465.
Example:
1 x 130,150,465 = 130,150,465
and
-1 x -130,150,465 = 130,150,465
Notice both answers equal 130,150,465
With that explanation out of the way, let's continue. Next, we take the number 130,150,465 and divide it by 2:
130,150,465 ÷ 2 = 65,075,232.5
If the quotient is a whole number, then 2 and 65,075,232.5 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 | 130,150,465 | |
| -1 | -130,150,465 |
Now, we try dividing 130,150,465 by 3:
130,150,465 ÷ 3 = 43,383,488.3333
If the quotient is a whole number, then 3 and 43,383,488.3333 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 | 130,150,465 | |
| -1 | -130,150,465 |
Let's try dividing by 4:
130,150,465 ÷ 4 = 32,537,616.25
If the quotient is a whole number, then 4 and 32,537,616.25 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 | 130,150,465 | |
| -1 | 130,150,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 131 | 215 | 655 | 4,621 | 5,633 | 23,105 | 28,165 | 198,703 | 605,351 | 993,515 | 3,026,755 | 26,030,093 | 130,150,465 |
| -1 | -5 | -43 | -131 | -215 | -655 | -4,621 | -5,633 | -23,105 | -28,165 | -198,703 | -605,351 | -993,515 | -3,026,755 | -26,030,093 | -130,150,465 |
