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 86,917,741, 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 | 86,917,741 | |
-1 | -86,917,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 86,917,741.
Example:
1 x 86,917,741 = 86,917,741
and
-1 x -86,917,741 = 86,917,741
Notice both answers equal 86,917,741
With that explanation out of the way, let's continue. Next, we take the number 86,917,741 and divide it by 2:
86,917,741 ÷ 2 = 43,458,870.5
If the quotient is a whole number, then 2 and 43,458,870.5 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 | 86,917,741 | |
-1 | -86,917,741 |
Now, we try dividing 86,917,741 by 3:
86,917,741 ÷ 3 = 28,972,580.3333
If the quotient is a whole number, then 3 and 28,972,580.3333 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 | 86,917,741 | |
-1 | -86,917,741 |
Let's try dividing by 4:
86,917,741 ÷ 4 = 21,729,435.25
If the quotient is a whole number, then 4 and 21,729,435.25 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 | 86,917,741 | |
-1 | 86,917,741 |
If you did it right, you will end up with this table:
1 | 61 | 1,424,881 | 86,917,741 |
-1 | -61 | -1,424,881 | -86,917,741 |
