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 253,706,005, 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 | 253,706,005 | |
| -1 | -253,706,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,706,005.
Example:
1 x 253,706,005 = 253,706,005
and
-1 x -253,706,005 = 253,706,005
Notice both answers equal 253,706,005
With that explanation out of the way, let's continue. Next, we take the number 253,706,005 and divide it by 2:
253,706,005 ÷ 2 = 126,853,002.5
If the quotient is a whole number, then 2 and 126,853,002.5 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 | 253,706,005 | |
| -1 | -253,706,005 |
Now, we try dividing 253,706,005 by 3:
253,706,005 ÷ 3 = 84,568,668.3333
If the quotient is a whole number, then 3 and 84,568,668.3333 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 | 253,706,005 | |
| -1 | -253,706,005 |
Let's try dividing by 4:
253,706,005 ÷ 4 = 63,426,501.25
If the quotient is a whole number, then 4 and 63,426,501.25 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 | 253,706,005 | |
| -1 | 253,706,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 269 | 1,345 | 1,883 | 9,415 | 26,947 | 134,735 | 188,629 | 943,145 | 7,248,743 | 36,243,715 | 50,741,201 | 253,706,005 |
| -1 | -5 | -7 | -35 | -269 | -1,345 | -1,883 | -9,415 | -26,947 | -134,735 | -188,629 | -943,145 | -7,248,743 | -36,243,715 | -50,741,201 | -253,706,005 |
