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 107,841,731, 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 | 107,841,731 | |
-1 | -107,841,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,841,731.
Example:
1 x 107,841,731 = 107,841,731
and
-1 x -107,841,731 = 107,841,731
Notice both answers equal 107,841,731
With that explanation out of the way, let's continue. Next, we take the number 107,841,731 and divide it by 2:
107,841,731 ÷ 2 = 53,920,865.5
If the quotient is a whole number, then 2 and 53,920,865.5 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 | 107,841,731 | |
-1 | -107,841,731 |
Now, we try dividing 107,841,731 by 3:
107,841,731 ÷ 3 = 35,947,243.6667
If the quotient is a whole number, then 3 and 35,947,243.6667 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 | 107,841,731 | |
-1 | -107,841,731 |
Let's try dividing by 4:
107,841,731 ÷ 4 = 26,960,432.75
If the quotient is a whole number, then 4 and 26,960,432.75 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 | 107,841,731 | |
-1 | 107,841,731 |
If you did it right, you will end up with this table:
1 | 5,011 | 21,521 | 107,841,731 |
-1 | -5,011 | -21,521 | -107,841,731 |
