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 51,115,553, 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 | 51,115,553 | |
-1 | -51,115,553 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,115,553.
Example:
1 x 51,115,553 = 51,115,553
and
-1 x -51,115,553 = 51,115,553
Notice both answers equal 51,115,553
With that explanation out of the way, let's continue. Next, we take the number 51,115,553 and divide it by 2:
51,115,553 ÷ 2 = 25,557,776.5
If the quotient is a whole number, then 2 and 25,557,776.5 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 | 51,115,553 | |
-1 | -51,115,553 |
Now, we try dividing 51,115,553 by 3:
51,115,553 ÷ 3 = 17,038,517.6667
If the quotient is a whole number, then 3 and 17,038,517.6667 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 | 51,115,553 | |
-1 | -51,115,553 |
Let's try dividing by 4:
51,115,553 ÷ 4 = 12,778,888.25
If the quotient is a whole number, then 4 and 12,778,888.25 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 | 51,115,553 | |
-1 | 51,115,553 |
If you did it right, you will end up with this table:
1 | 5,471 | 9,343 | 51,115,553 |
-1 | -5,471 | -9,343 | -51,115,553 |
