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 252,060,575, 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 | 252,060,575 | |
| -1 | -252,060,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,060,575.
Example:
1 x 252,060,575 = 252,060,575
and
-1 x -252,060,575 = 252,060,575
Notice both answers equal 252,060,575
With that explanation out of the way, let's continue. Next, we take the number 252,060,575 and divide it by 2:
252,060,575 ÷ 2 = 126,030,287.5
If the quotient is a whole number, then 2 and 126,030,287.5 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 | 252,060,575 | |
| -1 | -252,060,575 |
Now, we try dividing 252,060,575 by 3:
252,060,575 ÷ 3 = 84,020,191.6667
If the quotient is a whole number, then 3 and 84,020,191.6667 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 | 252,060,575 | |
| -1 | -252,060,575 |
Let's try dividing by 4:
252,060,575 ÷ 4 = 63,015,143.75
If the quotient is a whole number, then 4 and 63,015,143.75 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 | 252,060,575 | |
| -1 | 252,060,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 293 | 325 | 1,465 | 2,647 | 3,809 | 7,325 | 13,235 | 19,045 | 34,411 | 66,175 | 95,225 | 172,055 | 775,571 | 860,275 | 3,877,855 | 10,082,423 | 19,389,275 | 50,412,115 | 252,060,575 |
| -1 | -5 | -13 | -25 | -65 | -293 | -325 | -1,465 | -2,647 | -3,809 | -7,325 | -13,235 | -19,045 | -34,411 | -66,175 | -95,225 | -172,055 | -775,571 | -860,275 | -3,877,855 | -10,082,423 | -19,389,275 | -50,412,115 | -252,060,575 |
