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 64,605,367, 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 | 64,605,367 | |
| -1 | -64,605,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,605,367.
Example:
1 x 64,605,367 = 64,605,367
and
-1 x -64,605,367 = 64,605,367
Notice both answers equal 64,605,367
With that explanation out of the way, let's continue. Next, we take the number 64,605,367 and divide it by 2:
64,605,367 ÷ 2 = 32,302,683.5
If the quotient is a whole number, then 2 and 32,302,683.5 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 | 64,605,367 | |
| -1 | -64,605,367 |
Now, we try dividing 64,605,367 by 3:
64,605,367 ÷ 3 = 21,535,122.3333
If the quotient is a whole number, then 3 and 21,535,122.3333 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 | 64,605,367 | |
| -1 | -64,605,367 |
Let's try dividing by 4:
64,605,367 ÷ 4 = 16,151,341.75
If the quotient is a whole number, then 4 and 16,151,341.75 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 | 64,605,367 | |
| -1 | 64,605,367 |
If you did it right, you will end up with this table:
| 1 | 23 | 37 | 89 | 851 | 853 | 2,047 | 3,293 | 19,619 | 31,561 | 75,739 | 75,917 | 725,903 | 1,746,091 | 2,808,929 | 64,605,367 |
| -1 | -23 | -37 | -89 | -851 | -853 | -2,047 | -3,293 | -19,619 | -31,561 | -75,739 | -75,917 | -725,903 | -1,746,091 | -2,808,929 | -64,605,367 |
