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 77,232,857, 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 | 77,232,857 | |
-1 | -77,232,857 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 77,232,857.
Example:
1 x 77,232,857 = 77,232,857
and
-1 x -77,232,857 = 77,232,857
Notice both answers equal 77,232,857
With that explanation out of the way, let's continue. Next, we take the number 77,232,857 and divide it by 2:
77,232,857 ÷ 2 = 38,616,428.5
If the quotient is a whole number, then 2 and 38,616,428.5 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 | 77,232,857 | |
-1 | -77,232,857 |
Now, we try dividing 77,232,857 by 3:
77,232,857 ÷ 3 = 25,744,285.6667
If the quotient is a whole number, then 3 and 25,744,285.6667 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 | 77,232,857 | |
-1 | -77,232,857 |
Let's try dividing by 4:
77,232,857 ÷ 4 = 19,308,214.25
If the quotient is a whole number, then 4 and 19,308,214.25 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 | 77,232,857 | |
-1 | 77,232,857 |
If you did it right, you will end up with this table:
1 | 13 | 5,940,989 | 77,232,857 |
-1 | -13 | -5,940,989 | -77,232,857 |
