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 130,153,565, 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 | 130,153,565 | |
| -1 | -130,153,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,153,565.
Example:
1 x 130,153,565 = 130,153,565
and
-1 x -130,153,565 = 130,153,565
Notice both answers equal 130,153,565
With that explanation out of the way, let's continue. Next, we take the number 130,153,565 and divide it by 2:
130,153,565 ÷ 2 = 65,076,782.5
If the quotient is a whole number, then 2 and 65,076,782.5 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 | 130,153,565 | |
| -1 | -130,153,565 |
Now, we try dividing 130,153,565 by 3:
130,153,565 ÷ 3 = 43,384,521.6667
If the quotient is a whole number, then 3 and 43,384,521.6667 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 | 130,153,565 | |
| -1 | -130,153,565 |
Let's try dividing by 4:
130,153,565 ÷ 4 = 32,538,391.25
If the quotient is a whole number, then 4 and 32,538,391.25 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 | 130,153,565 | |
| -1 | 130,153,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 305 | 389 | 1,097 | 1,945 | 5,485 | 23,729 | 66,917 | 118,645 | 334,585 | 426,733 | 2,133,665 | 26,030,713 | 130,153,565 |
| -1 | -5 | -61 | -305 | -389 | -1,097 | -1,945 | -5,485 | -23,729 | -66,917 | -118,645 | -334,585 | -426,733 | -2,133,665 | -26,030,713 | -130,153,565 |
