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 65,414,125, 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 | 65,414,125 | |
| -1 | -65,414,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,414,125.
Example:
1 x 65,414,125 = 65,414,125
and
-1 x -65,414,125 = 65,414,125
Notice both answers equal 65,414,125
With that explanation out of the way, let's continue. Next, we take the number 65,414,125 and divide it by 2:
65,414,125 ÷ 2 = 32,707,062.5
If the quotient is a whole number, then 2 and 32,707,062.5 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 | 65,414,125 | |
| -1 | -65,414,125 |
Now, we try dividing 65,414,125 by 3:
65,414,125 ÷ 3 = 21,804,708.3333
If the quotient is a whole number, then 3 and 21,804,708.3333 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 | 65,414,125 | |
| -1 | -65,414,125 |
Let's try dividing by 4:
65,414,125 ÷ 4 = 16,353,531.25
If the quotient is a whole number, then 4 and 16,353,531.25 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 | 65,414,125 | |
| -1 | 65,414,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 74,759 | 373,795 | 523,313 | 1,868,975 | 2,616,565 | 9,344,875 | 13,082,825 | 65,414,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -74,759 | -373,795 | -523,313 | -1,868,975 | -2,616,565 | -9,344,875 | -13,082,825 | -65,414,125 |
