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 530,752,025, 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 | 530,752,025 | |
| -1 | -530,752,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,752,025.
Example:
1 x 530,752,025 = 530,752,025
and
-1 x -530,752,025 = 530,752,025
Notice both answers equal 530,752,025
With that explanation out of the way, let's continue. Next, we take the number 530,752,025 and divide it by 2:
530,752,025 ÷ 2 = 265,376,012.5
If the quotient is a whole number, then 2 and 265,376,012.5 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 | 530,752,025 | |
| -1 | -530,752,025 |
Now, we try dividing 530,752,025 by 3:
530,752,025 ÷ 3 = 176,917,341.6667
If the quotient is a whole number, then 3 and 176,917,341.6667 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 | 530,752,025 | |
| -1 | -530,752,025 |
Let's try dividing by 4:
530,752,025 ÷ 4 = 132,688,006.25
If the quotient is a whole number, then 4 and 132,688,006.25 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 | 530,752,025 | |
| -1 | 530,752,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 575 | 923,047 | 4,615,235 | 21,230,081 | 23,076,175 | 106,150,405 | 530,752,025 |
| -1 | -5 | -23 | -25 | -115 | -575 | -923,047 | -4,615,235 | -21,230,081 | -23,076,175 | -106,150,405 | -530,752,025 |
