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 238,128,263, 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 | 238,128,263 | |
| -1 | -238,128,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,128,263.
Example:
1 x 238,128,263 = 238,128,263
and
-1 x -238,128,263 = 238,128,263
Notice both answers equal 238,128,263
With that explanation out of the way, let's continue. Next, we take the number 238,128,263 and divide it by 2:
238,128,263 ÷ 2 = 119,064,131.5
If the quotient is a whole number, then 2 and 119,064,131.5 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 | 238,128,263 | |
| -1 | -238,128,263 |
Now, we try dividing 238,128,263 by 3:
238,128,263 ÷ 3 = 79,376,087.6667
If the quotient is a whole number, then 3 and 79,376,087.6667 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 | 238,128,263 | |
| -1 | -238,128,263 |
Let's try dividing by 4:
238,128,263 ÷ 4 = 59,532,065.75
If the quotient is a whole number, then 4 and 59,532,065.75 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 | 238,128,263 | |
| -1 | 238,128,263 |
If you did it right, you will end up with this table:
| 1 | 37 | 73 | 131 | 673 | 2,701 | 4,847 | 9,563 | 24,901 | 49,129 | 88,163 | 353,831 | 1,817,773 | 3,262,031 | 6,435,899 | 238,128,263 |
| -1 | -37 | -73 | -131 | -673 | -2,701 | -4,847 | -9,563 | -24,901 | -49,129 | -88,163 | -353,831 | -1,817,773 | -3,262,031 | -6,435,899 | -238,128,263 |
