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 21,464,735, 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 | 21,464,735 | |
| -1 | -21,464,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,464,735.
Example:
1 x 21,464,735 = 21,464,735
and
-1 x -21,464,735 = 21,464,735
Notice both answers equal 21,464,735
With that explanation out of the way, let's continue. Next, we take the number 21,464,735 and divide it by 2:
21,464,735 ÷ 2 = 10,732,367.5
If the quotient is a whole number, then 2 and 10,732,367.5 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 | 21,464,735 | |
| -1 | -21,464,735 |
Now, we try dividing 21,464,735 by 3:
21,464,735 ÷ 3 = 7,154,911.6667
If the quotient is a whole number, then 3 and 7,154,911.6667 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 | 21,464,735 | |
| -1 | -21,464,735 |
Let's try dividing by 4:
21,464,735 ÷ 4 = 5,366,183.75
If the quotient is a whole number, then 4 and 5,366,183.75 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 | 21,464,735 | |
| -1 | 21,464,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 107 | 265 | 535 | 757 | 3,785 | 5,671 | 28,355 | 40,121 | 80,999 | 200,605 | 404,995 | 4,292,947 | 21,464,735 |
| -1 | -5 | -53 | -107 | -265 | -535 | -757 | -3,785 | -5,671 | -28,355 | -40,121 | -80,999 | -200,605 | -404,995 | -4,292,947 | -21,464,735 |
