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 524,125,115, 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 | 524,125,115 | |
| -1 | -524,125,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 524,125,115.
Example:
1 x 524,125,115 = 524,125,115
and
-1 x -524,125,115 = 524,125,115
Notice both answers equal 524,125,115
With that explanation out of the way, let's continue. Next, we take the number 524,125,115 and divide it by 2:
524,125,115 ÷ 2 = 262,062,557.5
If the quotient is a whole number, then 2 and 262,062,557.5 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 | 524,125,115 | |
| -1 | -524,125,115 |
Now, we try dividing 524,125,115 by 3:
524,125,115 ÷ 3 = 174,708,371.6667
If the quotient is a whole number, then 3 and 174,708,371.6667 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 | 524,125,115 | |
| -1 | -524,125,115 |
Let's try dividing by 4:
524,125,115 ÷ 4 = 131,031,278.75
If the quotient is a whole number, then 4 and 131,031,278.75 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 | 524,125,115 | |
| -1 | 524,125,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 305 | 1,151 | 1,493 | 5,755 | 7,465 | 70,211 | 91,073 | 351,055 | 455,365 | 1,718,443 | 8,592,215 | 104,825,023 | 524,125,115 |
| -1 | -5 | -61 | -305 | -1,151 | -1,493 | -5,755 | -7,465 | -70,211 | -91,073 | -351,055 | -455,365 | -1,718,443 | -8,592,215 | -104,825,023 | -524,125,115 |
