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 126,801,763, 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 | 126,801,763 | |
| -1 | -126,801,763 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 126,801,763.
Example:
1 x 126,801,763 = 126,801,763
and
-1 x -126,801,763 = 126,801,763
Notice both answers equal 126,801,763
With that explanation out of the way, let's continue. Next, we take the number 126,801,763 and divide it by 2:
126,801,763 ÷ 2 = 63,400,881.5
If the quotient is a whole number, then 2 and 63,400,881.5 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 | 126,801,763 | |
| -1 | -126,801,763 |
Now, we try dividing 126,801,763 by 3:
126,801,763 ÷ 3 = 42,267,254.3333
If the quotient is a whole number, then 3 and 42,267,254.3333 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 | 126,801,763 | |
| -1 | -126,801,763 |
Let's try dividing by 4:
126,801,763 ÷ 4 = 31,700,440.75
If the quotient is a whole number, then 4 and 31,700,440.75 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 | 126,801,763 | |
| -1 | 126,801,763 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 101 | 209 | 1,111 | 1,919 | 6,007 | 21,109 | 66,077 | 114,133 | 606,707 | 1,255,463 | 6,673,777 | 11,527,433 | 126,801,763 |
| -1 | -11 | -19 | -101 | -209 | -1,111 | -1,919 | -6,007 | -21,109 | -66,077 | -114,133 | -606,707 | -1,255,463 | -6,673,777 | -11,527,433 | -126,801,763 |
