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 130,235,435, 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 | 130,235,435 | |
| -1 | -130,235,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,235,435.
Example:
1 x 130,235,435 = 130,235,435
and
-1 x -130,235,435 = 130,235,435
Notice both answers equal 130,235,435
With that explanation out of the way, let's continue. Next, we take the number 130,235,435 and divide it by 2:
130,235,435 ÷ 2 = 65,117,717.5
If the quotient is a whole number, then 2 and 65,117,717.5 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 | 130,235,435 | |
| -1 | -130,235,435 |
Now, we try dividing 130,235,435 by 3:
130,235,435 ÷ 3 = 43,411,811.6667
If the quotient is a whole number, then 3 and 43,411,811.6667 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 | 130,235,435 | |
| -1 | -130,235,435 |
Let's try dividing by 4:
130,235,435 ÷ 4 = 32,558,858.75
If the quotient is a whole number, then 4 and 32,558,858.75 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 | 130,235,435 | |
| -1 | 130,235,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 193 | 965 | 2,123 | 10,615 | 12,269 | 61,345 | 134,959 | 674,795 | 2,367,917 | 11,839,585 | 26,047,087 | 130,235,435 |
| -1 | -5 | -11 | -55 | -193 | -965 | -2,123 | -10,615 | -12,269 | -61,345 | -134,959 | -674,795 | -2,367,917 | -11,839,585 | -26,047,087 | -130,235,435 |
