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 35,235,421, 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 | 35,235,421 | |
| -1 | -35,235,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 35,235,421.
Example:
1 x 35,235,421 = 35,235,421
and
-1 x -35,235,421 = 35,235,421
Notice both answers equal 35,235,421
With that explanation out of the way, let's continue. Next, we take the number 35,235,421 and divide it by 2:
35,235,421 ÷ 2 = 17,617,710.5
If the quotient is a whole number, then 2 and 17,617,710.5 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 | 35,235,421 | |
| -1 | -35,235,421 |
Now, we try dividing 35,235,421 by 3:
35,235,421 ÷ 3 = 11,745,140.3333
If the quotient is a whole number, then 3 and 11,745,140.3333 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 | 35,235,421 | |
| -1 | -35,235,421 |
Let's try dividing by 4:
35,235,421 ÷ 4 = 8,808,855.25
If the quotient is a whole number, then 4 and 8,808,855.25 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 | 35,235,421 | |
| -1 | 35,235,421 |
If you did it right, you will end up with this table:
| 1 | 13 | 73 | 107 | 347 | 949 | 1,391 | 4,511 | 7,811 | 25,331 | 37,129 | 101,543 | 329,303 | 482,677 | 2,710,417 | 35,235,421 |
| -1 | -13 | -73 | -107 | -347 | -949 | -1,391 | -4,511 | -7,811 | -25,331 | -37,129 | -101,543 | -329,303 | -482,677 | -2,710,417 | -35,235,421 |
