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 65,501,683, 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 | 65,501,683 | |
| -1 | -65,501,683 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,501,683.
Example:
1 x 65,501,683 = 65,501,683
and
-1 x -65,501,683 = 65,501,683
Notice both answers equal 65,501,683
With that explanation out of the way, let's continue. Next, we take the number 65,501,683 and divide it by 2:
65,501,683 ÷ 2 = 32,750,841.5
If the quotient is a whole number, then 2 and 32,750,841.5 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 | 65,501,683 | |
| -1 | -65,501,683 |
Now, we try dividing 65,501,683 by 3:
65,501,683 ÷ 3 = 21,833,894.3333
If the quotient is a whole number, then 3 and 21,833,894.3333 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 | 65,501,683 | |
| -1 | -65,501,683 |
Let's try dividing by 4:
65,501,683 ÷ 4 = 16,375,420.75
If the quotient is a whole number, then 4 and 16,375,420.75 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 | 65,501,683 | |
| -1 | 65,501,683 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 509 | 521 | 6,617 | 6,773 | 9,671 | 9,899 | 125,723 | 128,687 | 265,189 | 3,447,457 | 5,038,591 | 65,501,683 |
| -1 | -13 | -19 | -247 | -509 | -521 | -6,617 | -6,773 | -9,671 | -9,899 | -125,723 | -128,687 | -265,189 | -3,447,457 | -5,038,591 | -65,501,683 |
