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 65,043,629, 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 | 65,043,629 | |
| -1 | -65,043,629 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,043,629.
Example:
1 x 65,043,629 = 65,043,629
and
-1 x -65,043,629 = 65,043,629
Notice both answers equal 65,043,629
With that explanation out of the way, let's continue. Next, we take the number 65,043,629 and divide it by 2:
65,043,629 ÷ 2 = 32,521,814.5
If the quotient is a whole number, then 2 and 32,521,814.5 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 | 65,043,629 | |
| -1 | -65,043,629 |
Now, we try dividing 65,043,629 by 3:
65,043,629 ÷ 3 = 21,681,209.6667
If the quotient is a whole number, then 3 and 21,681,209.6667 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 | 65,043,629 | |
| -1 | -65,043,629 |
Let's try dividing by 4:
65,043,629 ÷ 4 = 16,260,907.25
If the quotient is a whole number, then 4 and 16,260,907.25 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 | 65,043,629 | |
| -1 | 65,043,629 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 49 | 61 | 329 | 427 | 463 | 2,303 | 2,867 | 2,989 | 3,241 | 20,069 | 21,761 | 22,687 | 28,243 | 140,483 | 152,327 | 197,701 | 1,066,289 | 1,327,421 | 1,383,907 | 9,291,947 | 65,043,629 |
| -1 | -7 | -47 | -49 | -61 | -329 | -427 | -463 | -2,303 | -2,867 | -2,989 | -3,241 | -20,069 | -21,761 | -22,687 | -28,243 | -140,483 | -152,327 | -197,701 | -1,066,289 | -1,327,421 | -1,383,907 | -9,291,947 | -65,043,629 |
