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 64,122,317, 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 | 64,122,317 | |
| -1 | -64,122,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,122,317.
Example:
1 x 64,122,317 = 64,122,317
and
-1 x -64,122,317 = 64,122,317
Notice both answers equal 64,122,317
With that explanation out of the way, let's continue. Next, we take the number 64,122,317 and divide it by 2:
64,122,317 ÷ 2 = 32,061,158.5
If the quotient is a whole number, then 2 and 32,061,158.5 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 | 64,122,317 | |
| -1 | -64,122,317 |
Now, we try dividing 64,122,317 by 3:
64,122,317 ÷ 3 = 21,374,105.6667
If the quotient is a whole number, then 3 and 21,374,105.6667 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 | 64,122,317 | |
| -1 | -64,122,317 |
Let's try dividing by 4:
64,122,317 ÷ 4 = 16,030,579.25
If the quotient is a whole number, then 4 and 16,030,579.25 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 | 64,122,317 | |
| -1 | 64,122,317 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 569 | 947 | 3,983 | 6,629 | 9,673 | 16,099 | 67,711 | 112,693 | 538,843 | 3,771,901 | 9,160,331 | 64,122,317 |
| -1 | -7 | -17 | -119 | -569 | -947 | -3,983 | -6,629 | -9,673 | -16,099 | -67,711 | -112,693 | -538,843 | -3,771,901 | -9,160,331 | -64,122,317 |
