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 136,871,507, 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 | 136,871,507 | |
-1 | -136,871,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 136,871,507.
Example:
1 x 136,871,507 = 136,871,507
and
-1 x -136,871,507 = 136,871,507
Notice both answers equal 136,871,507
With that explanation out of the way, let's continue. Next, we take the number 136,871,507 and divide it by 2:
136,871,507 ÷ 2 = 68,435,753.5
If the quotient is a whole number, then 2 and 68,435,753.5 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 | 136,871,507 | |
-1 | -136,871,507 |
Now, we try dividing 136,871,507 by 3:
136,871,507 ÷ 3 = 45,623,835.6667
If the quotient is a whole number, then 3 and 45,623,835.6667 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 | 136,871,507 | |
-1 | -136,871,507 |
Let's try dividing by 4:
136,871,507 ÷ 4 = 34,217,876.75
If the quotient is a whole number, then 4 and 34,217,876.75 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 | 136,871,507 | |
-1 | 136,871,507 |
If you did it right, you will end up with this table:
1 | 9,151 | 14,957 | 136,871,507 |
-1 | -9,151 | -14,957 | -136,871,507 |
