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 64,014,635, 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 | 64,014,635 | |
| -1 | -64,014,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,014,635.
Example:
1 x 64,014,635 = 64,014,635
and
-1 x -64,014,635 = 64,014,635
Notice both answers equal 64,014,635
With that explanation out of the way, let's continue. Next, we take the number 64,014,635 and divide it by 2:
64,014,635 ÷ 2 = 32,007,317.5
If the quotient is a whole number, then 2 and 32,007,317.5 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 | 64,014,635 | |
| -1 | -64,014,635 |
Now, we try dividing 64,014,635 by 3:
64,014,635 ÷ 3 = 21,338,211.6667
If the quotient is a whole number, then 3 and 21,338,211.6667 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 | 64,014,635 | |
| -1 | -64,014,635 |
Let's try dividing by 4:
64,014,635 ÷ 4 = 16,003,658.75
If the quotient is a whole number, then 4 and 16,003,658.75 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 | 64,014,635 | |
| -1 | 64,014,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 409 | 1,361 | 2,045 | 6,805 | 9,407 | 31,303 | 47,035 | 156,515 | 556,649 | 2,783,245 | 12,802,927 | 64,014,635 |
| -1 | -5 | -23 | -115 | -409 | -1,361 | -2,045 | -6,805 | -9,407 | -31,303 | -47,035 | -156,515 | -556,649 | -2,783,245 | -12,802,927 | -64,014,635 |
