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 252,342,025, 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 | 252,342,025 | |
| -1 | -252,342,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,342,025.
Example:
1 x 252,342,025 = 252,342,025
and
-1 x -252,342,025 = 252,342,025
Notice both answers equal 252,342,025
With that explanation out of the way, let's continue. Next, we take the number 252,342,025 and divide it by 2:
252,342,025 ÷ 2 = 126,171,012.5
If the quotient is a whole number, then 2 and 126,171,012.5 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 | 252,342,025 | |
| -1 | -252,342,025 |
Now, we try dividing 252,342,025 by 3:
252,342,025 ÷ 3 = 84,114,008.3333
If the quotient is a whole number, then 3 and 84,114,008.3333 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 | 252,342,025 | |
| -1 | -252,342,025 |
Let's try dividing by 4:
252,342,025 ÷ 4 = 63,085,506.25
If the quotient is a whole number, then 4 and 63,085,506.25 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 | 252,342,025 | |
| -1 | 252,342,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 131 | 325 | 655 | 1,703 | 3,275 | 5,927 | 8,515 | 29,635 | 42,575 | 77,051 | 148,175 | 385,255 | 776,437 | 1,926,275 | 3,882,185 | 10,093,681 | 19,410,925 | 50,468,405 | 252,342,025 |
| -1 | -5 | -13 | -25 | -65 | -131 | -325 | -655 | -1,703 | -3,275 | -5,927 | -8,515 | -29,635 | -42,575 | -77,051 | -148,175 | -385,255 | -776,437 | -1,926,275 | -3,882,185 | -10,093,681 | -19,410,925 | -50,468,405 | -252,342,025 |
