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 87,766,841, 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 | 87,766,841 | |
-1 | -87,766,841 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 87,766,841.
Example:
1 x 87,766,841 = 87,766,841
and
-1 x -87,766,841 = 87,766,841
Notice both answers equal 87,766,841
With that explanation out of the way, let's continue. Next, we take the number 87,766,841 and divide it by 2:
87,766,841 ÷ 2 = 43,883,420.5
If the quotient is a whole number, then 2 and 43,883,420.5 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 | 87,766,841 | |
-1 | -87,766,841 |
Now, we try dividing 87,766,841 by 3:
87,766,841 ÷ 3 = 29,255,613.6667
If the quotient is a whole number, then 3 and 29,255,613.6667 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 | 87,766,841 | |
-1 | -87,766,841 |
Let's try dividing by 4:
87,766,841 ÷ 4 = 21,941,710.25
If the quotient is a whole number, then 4 and 21,941,710.25 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 | 87,766,841 | |
-1 | 87,766,841 |
If you did it right, you will end up with this table:
1 | 977 | 89,833 | 87,766,841 |
-1 | -977 | -89,833 | -87,766,841 |
