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 116,126,549, 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 | 116,126,549 | |
| -1 | -116,126,549 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,126,549.
Example:
1 x 116,126,549 = 116,126,549
and
-1 x -116,126,549 = 116,126,549
Notice both answers equal 116,126,549
With that explanation out of the way, let's continue. Next, we take the number 116,126,549 and divide it by 2:
116,126,549 ÷ 2 = 58,063,274.5
If the quotient is a whole number, then 2 and 58,063,274.5 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 | 116,126,549 | |
| -1 | -116,126,549 |
Now, we try dividing 116,126,549 by 3:
116,126,549 ÷ 3 = 38,708,849.6667
If the quotient is a whole number, then 3 and 38,708,849.6667 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 | 116,126,549 | |
| -1 | -116,126,549 |
Let's try dividing by 4:
116,126,549 ÷ 4 = 29,031,637.25
If the quotient is a whole number, then 4 and 29,031,637.25 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 | 116,126,549 | |
| -1 | 116,126,549 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,181 | 1,277 | 8,267 | 8,939 | 12,991 | 14,047 | 90,937 | 98,329 | 1,508,137 | 10,556,959 | 16,589,507 | 116,126,549 |
| -1 | -7 | -11 | -77 | -1,181 | -1,277 | -8,267 | -8,939 | -12,991 | -14,047 | -90,937 | -98,329 | -1,508,137 | -10,556,959 | -16,589,507 | -116,126,549 |
