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 35,700,065, 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 | 35,700,065 | |
| -1 | -35,700,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,700,065.
Example:
1 x 35,700,065 = 35,700,065
and
-1 x -35,700,065 = 35,700,065
Notice both answers equal 35,700,065
With that explanation out of the way, let's continue. Next, we take the number 35,700,065 and divide it by 2:
35,700,065 ÷ 2 = 17,850,032.5
If the quotient is a whole number, then 2 and 17,850,032.5 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 | 35,700,065 | |
| -1 | -35,700,065 |
Now, we try dividing 35,700,065 by 3:
35,700,065 ÷ 3 = 11,900,021.6667
If the quotient is a whole number, then 3 and 11,900,021.6667 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 | 35,700,065 | |
| -1 | -35,700,065 |
Let's try dividing by 4:
35,700,065 ÷ 4 = 8,925,016.25
If the quotient is a whole number, then 4 and 8,925,016.25 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 | 35,700,065 | |
| -1 | 35,700,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 139 | 155 | 695 | 1,657 | 4,309 | 8,285 | 21,545 | 51,367 | 230,323 | 256,835 | 1,151,615 | 7,140,013 | 35,700,065 |
| -1 | -5 | -31 | -139 | -155 | -695 | -1,657 | -4,309 | -8,285 | -21,545 | -51,367 | -230,323 | -256,835 | -1,151,615 | -7,140,013 | -35,700,065 |
