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 253,668,035, 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 | 253,668,035 | |
| -1 | -253,668,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,668,035.
Example:
1 x 253,668,035 = 253,668,035
and
-1 x -253,668,035 = 253,668,035
Notice both answers equal 253,668,035
With that explanation out of the way, let's continue. Next, we take the number 253,668,035 and divide it by 2:
253,668,035 ÷ 2 = 126,834,017.5
If the quotient is a whole number, then 2 and 126,834,017.5 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 | 253,668,035 | |
| -1 | -253,668,035 |
Now, we try dividing 253,668,035 by 3:
253,668,035 ÷ 3 = 84,556,011.6667
If the quotient is a whole number, then 3 and 84,556,011.6667 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 | 253,668,035 | |
| -1 | -253,668,035 |
Let's try dividing by 4:
253,668,035 ÷ 4 = 63,417,008.75
If the quotient is a whole number, then 4 and 63,417,008.75 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 | 253,668,035 | |
| -1 | 253,668,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 197 | 985 | 4,531 | 11,197 | 22,655 | 55,985 | 257,531 | 1,287,655 | 2,205,809 | 11,029,045 | 50,733,607 | 253,668,035 |
| -1 | -5 | -23 | -115 | -197 | -985 | -4,531 | -11,197 | -22,655 | -55,985 | -257,531 | -1,287,655 | -2,205,809 | -11,029,045 | -50,733,607 | -253,668,035 |
