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 100,770,371, 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 | 100,770,371 | |
| -1 | -100,770,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,770,371.
Example:
1 x 100,770,371 = 100,770,371
and
-1 x -100,770,371 = 100,770,371
Notice both answers equal 100,770,371
With that explanation out of the way, let's continue. Next, we take the number 100,770,371 and divide it by 2:
100,770,371 ÷ 2 = 50,385,185.5
If the quotient is a whole number, then 2 and 50,385,185.5 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 | 100,770,371 | |
| -1 | -100,770,371 |
Now, we try dividing 100,770,371 by 3:
100,770,371 ÷ 3 = 33,590,123.6667
If the quotient is a whole number, then 3 and 33,590,123.6667 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 | 100,770,371 | |
| -1 | -100,770,371 |
Let's try dividing by 4:
100,770,371 ÷ 4 = 25,192,592.75
If the quotient is a whole number, then 4 and 25,192,592.75 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 | 100,770,371 | |
| -1 | 100,770,371 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 71 | 559 | 923 | 2,539 | 3,053 | 33,007 | 39,689 | 109,177 | 180,269 | 1,419,301 | 2,343,497 | 7,751,567 | 100,770,371 |
| -1 | -13 | -43 | -71 | -559 | -923 | -2,539 | -3,053 | -33,007 | -39,689 | -109,177 | -180,269 | -1,419,301 | -2,343,497 | -7,751,567 | -100,770,371 |
