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 107,157,743, 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 | 107,157,743 | |
| -1 | -107,157,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,157,743.
Example:
1 x 107,157,743 = 107,157,743
and
-1 x -107,157,743 = 107,157,743
Notice both answers equal 107,157,743
With that explanation out of the way, let's continue. Next, we take the number 107,157,743 and divide it by 2:
107,157,743 ÷ 2 = 53,578,871.5
If the quotient is a whole number, then 2 and 53,578,871.5 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 | 107,157,743 | |
| -1 | -107,157,743 |
Now, we try dividing 107,157,743 by 3:
107,157,743 ÷ 3 = 35,719,247.6667
If the quotient is a whole number, then 3 and 35,719,247.6667 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 | 107,157,743 | |
| -1 | -107,157,743 |
Let's try dividing by 4:
107,157,743 ÷ 4 = 26,789,435.75
If the quotient is a whole number, then 4 and 26,789,435.75 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 | 107,157,743 | |
| -1 | 107,157,743 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 679 | 1,067 | 7,469 | 14,347 | 100,429 | 157,817 | 1,104,719 | 1,391,659 | 9,741,613 | 15,308,249 | 107,157,743 |
| -1 | -7 | -11 | -77 | -97 | -679 | -1,067 | -7,469 | -14,347 | -100,429 | -157,817 | -1,104,719 | -1,391,659 | -9,741,613 | -15,308,249 | -107,157,743 |
