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 126,615,223, 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 | 126,615,223 | |
| -1 | -126,615,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,615,223.
Example:
1 x 126,615,223 = 126,615,223
and
-1 x -126,615,223 = 126,615,223
Notice both answers equal 126,615,223
With that explanation out of the way, let's continue. Next, we take the number 126,615,223 and divide it by 2:
126,615,223 ÷ 2 = 63,307,611.5
If the quotient is a whole number, then 2 and 63,307,611.5 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 | 126,615,223 | |
| -1 | -126,615,223 |
Now, we try dividing 126,615,223 by 3:
126,615,223 ÷ 3 = 42,205,074.3333
If the quotient is a whole number, then 3 and 42,205,074.3333 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 | 126,615,223 | |
| -1 | -126,615,223 |
Let's try dividing by 4:
126,615,223 ÷ 4 = 31,653,805.75
If the quotient is a whole number, then 4 and 31,653,805.75 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 | 126,615,223 | |
| -1 | 126,615,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 71 | 373 | 497 | 683 | 2,611 | 4,781 | 26,483 | 48,493 | 185,381 | 254,759 | 339,451 | 1,783,313 | 18,087,889 | 126,615,223 |
| -1 | -7 | -71 | -373 | -497 | -683 | -2,611 | -4,781 | -26,483 | -48,493 | -185,381 | -254,759 | -339,451 | -1,783,313 | -18,087,889 | -126,615,223 |
