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 65,406,437, 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 | 65,406,437 | |
-1 | -65,406,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,406,437.
Example:
1 x 65,406,437 = 65,406,437
and
-1 x -65,406,437 = 65,406,437
Notice both answers equal 65,406,437
With that explanation out of the way, let's continue. Next, we take the number 65,406,437 and divide it by 2:
65,406,437 ÷ 2 = 32,703,218.5
If the quotient is a whole number, then 2 and 32,703,218.5 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 | 65,406,437 | |
-1 | -65,406,437 |
Now, we try dividing 65,406,437 by 3:
65,406,437 ÷ 3 = 21,802,145.6667
If the quotient is a whole number, then 3 and 21,802,145.6667 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 | 65,406,437 | |
-1 | -65,406,437 |
Let's try dividing by 4:
65,406,437 ÷ 4 = 16,351,609.25
If the quotient is a whole number, then 4 and 16,351,609.25 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 | 65,406,437 | |
-1 | 65,406,437 |
If you did it right, you will end up with this table:
1 | 2,417 | 27,061 | 65,406,437 |
-1 | -2,417 | -27,061 | -65,406,437 |
