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 252,522,319, 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 | 252,522,319 | |
| -1 | -252,522,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,522,319.
Example:
1 x 252,522,319 = 252,522,319
and
-1 x -252,522,319 = 252,522,319
Notice both answers equal 252,522,319
With that explanation out of the way, let's continue. Next, we take the number 252,522,319 and divide it by 2:
252,522,319 ÷ 2 = 126,261,159.5
If the quotient is a whole number, then 2 and 126,261,159.5 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 | 252,522,319 | |
| -1 | -252,522,319 |
Now, we try dividing 252,522,319 by 3:
252,522,319 ÷ 3 = 84,174,106.3333
If the quotient is a whole number, then 3 and 84,174,106.3333 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 | 252,522,319 | |
| -1 | -252,522,319 |
Let's try dividing by 4:
252,522,319 ÷ 4 = 63,130,579.75
If the quotient is a whole number, then 4 and 63,130,579.75 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 | 252,522,319 | |
| -1 | 252,522,319 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 577 | 607 | 721 | 4,039 | 4,249 | 59,431 | 62,521 | 350,239 | 416,017 | 437,647 | 2,451,673 | 36,074,617 | 252,522,319 |
| -1 | -7 | -103 | -577 | -607 | -721 | -4,039 | -4,249 | -59,431 | -62,521 | -350,239 | -416,017 | -437,647 | -2,451,673 | -36,074,617 | -252,522,319 |
