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 65,436,409, 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 | 65,436,409 | |
-1 | -65,436,409 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,436,409.
Example:
1 x 65,436,409 = 65,436,409
and
-1 x -65,436,409 = 65,436,409
Notice both answers equal 65,436,409
With that explanation out of the way, let's continue. Next, we take the number 65,436,409 and divide it by 2:
65,436,409 ÷ 2 = 32,718,204.5
If the quotient is a whole number, then 2 and 32,718,204.5 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 | 65,436,409 | |
-1 | -65,436,409 |
Now, we try dividing 65,436,409 by 3:
65,436,409 ÷ 3 = 21,812,136.3333
If the quotient is a whole number, then 3 and 21,812,136.3333 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 | 65,436,409 | |
-1 | -65,436,409 |
Let's try dividing by 4:
65,436,409 ÷ 4 = 16,359,102.25
If the quotient is a whole number, then 4 and 16,359,102.25 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 | 65,436,409 | |
-1 | 65,436,409 |
If you did it right, you will end up with this table:
1 | 191 | 342,599 | 65,436,409 |
-1 | -191 | -342,599 | -65,436,409 |
