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 252,210,673, 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 | 252,210,673 | |
| -1 | -252,210,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 252,210,673.
Example:
1 x 252,210,673 = 252,210,673
and
-1 x -252,210,673 = 252,210,673
Notice both answers equal 252,210,673
With that explanation out of the way, let's continue. Next, we take the number 252,210,673 and divide it by 2:
252,210,673 ÷ 2 = 126,105,336.5
If the quotient is a whole number, then 2 and 126,105,336.5 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 | 252,210,673 | |
| -1 | -252,210,673 |
Now, we try dividing 252,210,673 by 3:
252,210,673 ÷ 3 = 84,070,224.3333
If the quotient is a whole number, then 3 and 84,070,224.3333 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 | 252,210,673 | |
| -1 | -252,210,673 |
Let's try dividing by 4:
252,210,673 ÷ 4 = 63,052,668.25
If the quotient is a whole number, then 4 and 63,052,668.25 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 | 252,210,673 | |
| -1 | 252,210,673 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 71 | 143 | 781 | 923 | 10,153 | 24,841 | 273,251 | 322,933 | 1,763,711 | 3,552,263 | 19,400,821 | 22,928,243 | 252,210,673 |
| -1 | -11 | -13 | -71 | -143 | -781 | -923 | -10,153 | -24,841 | -273,251 | -322,933 | -1,763,711 | -3,552,263 | -19,400,821 | -22,928,243 | -252,210,673 |
