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 51,067,211, 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 | 51,067,211 | |
-1 | -51,067,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,067,211.
Example:
1 x 51,067,211 = 51,067,211
and
-1 x -51,067,211 = 51,067,211
Notice both answers equal 51,067,211
With that explanation out of the way, let's continue. Next, we take the number 51,067,211 and divide it by 2:
51,067,211 ÷ 2 = 25,533,605.5
If the quotient is a whole number, then 2 and 25,533,605.5 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 | 51,067,211 | |
-1 | -51,067,211 |
Now, we try dividing 51,067,211 by 3:
51,067,211 ÷ 3 = 17,022,403.6667
If the quotient is a whole number, then 3 and 17,022,403.6667 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 | 51,067,211 | |
-1 | -51,067,211 |
Let's try dividing by 4:
51,067,211 ÷ 4 = 12,766,802.75
If the quotient is a whole number, then 4 and 12,766,802.75 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 | 51,067,211 | |
-1 | 51,067,211 |
If you did it right, you will end up with this table:
1 | 13 | 3,928,247 | 51,067,211 |
-1 | -13 | -3,928,247 | -51,067,211 |
