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 106,542,631, 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 | 106,542,631 | |
-1 | -106,542,631 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,542,631.
Example:
1 x 106,542,631 = 106,542,631
and
-1 x -106,542,631 = 106,542,631
Notice both answers equal 106,542,631
With that explanation out of the way, let's continue. Next, we take the number 106,542,631 and divide it by 2:
106,542,631 ÷ 2 = 53,271,315.5
If the quotient is a whole number, then 2 and 53,271,315.5 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 | 106,542,631 | |
-1 | -106,542,631 |
Now, we try dividing 106,542,631 by 3:
106,542,631 ÷ 3 = 35,514,210.3333
If the quotient is a whole number, then 3 and 35,514,210.3333 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 | 106,542,631 | |
-1 | -106,542,631 |
Let's try dividing by 4:
106,542,631 ÷ 4 = 26,635,657.75
If the quotient is a whole number, then 4 and 26,635,657.75 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 | 106,542,631 | |
-1 | 106,542,631 |
If you did it right, you will end up with this table:
1 | 13 | 8,195,587 | 106,542,631 |
-1 | -13 | -8,195,587 | -106,542,631 |
