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 64,026,335, 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 | 64,026,335 | |
| -1 | -64,026,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,026,335.
Example:
1 x 64,026,335 = 64,026,335
and
-1 x -64,026,335 = 64,026,335
Notice both answers equal 64,026,335
With that explanation out of the way, let's continue. Next, we take the number 64,026,335 and divide it by 2:
64,026,335 ÷ 2 = 32,013,167.5
If the quotient is a whole number, then 2 and 32,013,167.5 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 | 64,026,335 | |
| -1 | -64,026,335 |
Now, we try dividing 64,026,335 by 3:
64,026,335 ÷ 3 = 21,342,111.6667
If the quotient is a whole number, then 3 and 21,342,111.6667 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 | 64,026,335 | |
| -1 | -64,026,335 |
Let's try dividing by 4:
64,026,335 ÷ 4 = 16,006,583.75
If the quotient is a whole number, then 4 and 16,006,583.75 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 | 64,026,335 | |
| -1 | 64,026,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 251 | 1,255 | 3,001 | 4,267 | 15,005 | 21,335 | 51,017 | 255,085 | 753,251 | 3,766,255 | 12,805,267 | 64,026,335 |
| -1 | -5 | -17 | -85 | -251 | -1,255 | -3,001 | -4,267 | -15,005 | -21,335 | -51,017 | -255,085 | -753,251 | -3,766,255 | -12,805,267 | -64,026,335 |
