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 130,514,557, 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 | 130,514,557 | |
| -1 | -130,514,557 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 130,514,557.
Example:
1 x 130,514,557 = 130,514,557
and
-1 x -130,514,557 = 130,514,557
Notice both answers equal 130,514,557
With that explanation out of the way, let's continue. Next, we take the number 130,514,557 and divide it by 2:
130,514,557 ÷ 2 = 65,257,278.5
If the quotient is a whole number, then 2 and 65,257,278.5 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 | 130,514,557 | |
| -1 | -130,514,557 |
Now, we try dividing 130,514,557 by 3:
130,514,557 ÷ 3 = 43,504,852.3333
If the quotient is a whole number, then 3 and 43,504,852.3333 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 | 130,514,557 | |
| -1 | -130,514,557 |
Let's try dividing by 4:
130,514,557 ÷ 4 = 32,628,639.25
If the quotient is a whole number, then 4 and 32,628,639.25 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 | 130,514,557 | |
| -1 | 130,514,557 |
If you did it right, you will end up with this table:
| 1 | 31 | 79 | 137 | 389 | 2,449 | 4,247 | 10,823 | 12,059 | 30,731 | 53,293 | 335,513 | 952,661 | 1,652,083 | 4,210,147 | 130,514,557 |
| -1 | -31 | -79 | -137 | -389 | -2,449 | -4,247 | -10,823 | -12,059 | -30,731 | -53,293 | -335,513 | -952,661 | -1,652,083 | -4,210,147 | -130,514,557 |
