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 65,897,113, 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 | 65,897,113 | |
| -1 | -65,897,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,897,113.
Example:
1 x 65,897,113 = 65,897,113
and
-1 x -65,897,113 = 65,897,113
Notice both answers equal 65,897,113
With that explanation out of the way, let's continue. Next, we take the number 65,897,113 and divide it by 2:
65,897,113 ÷ 2 = 32,948,556.5
If the quotient is a whole number, then 2 and 32,948,556.5 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 | 65,897,113 | |
| -1 | -65,897,113 |
Now, we try dividing 65,897,113 by 3:
65,897,113 ÷ 3 = 21,965,704.3333
If the quotient is a whole number, then 3 and 21,965,704.3333 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 | 65,897,113 | |
| -1 | -65,897,113 |
Let's try dividing by 4:
65,897,113 ÷ 4 = 16,474,278.25
If the quotient is a whole number, then 4 and 16,474,278.25 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 | 65,897,113 | |
| -1 | 65,897,113 |
If you did it right, you will end up with this table:
| 1 | 43 | 67 | 89 | 257 | 2,881 | 3,827 | 5,963 | 11,051 | 17,219 | 22,873 | 256,409 | 740,417 | 983,539 | 1,532,491 | 65,897,113 |
| -1 | -43 | -67 | -89 | -257 | -2,881 | -3,827 | -5,963 | -11,051 | -17,219 | -22,873 | -256,409 | -740,417 | -983,539 | -1,532,491 | -65,897,113 |
