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 21,736,435, 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 | 21,736,435 | |
| -1 | -21,736,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,736,435.
Example:
1 x 21,736,435 = 21,736,435
and
-1 x -21,736,435 = 21,736,435
Notice both answers equal 21,736,435
With that explanation out of the way, let's continue. Next, we take the number 21,736,435 and divide it by 2:
21,736,435 ÷ 2 = 10,868,217.5
If the quotient is a whole number, then 2 and 10,868,217.5 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 | 21,736,435 | |
| -1 | -21,736,435 |
Now, we try dividing 21,736,435 by 3:
21,736,435 ÷ 3 = 7,245,478.3333
If the quotient is a whole number, then 3 and 7,245,478.3333 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 | 21,736,435 | |
| -1 | -21,736,435 |
Let's try dividing by 4:
21,736,435 ÷ 4 = 5,434,108.75
If the quotient is a whole number, then 4 and 5,434,108.75 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 | 21,736,435 | |
| -1 | 21,736,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 61 | 305 | 427 | 2,135 | 10,181 | 50,905 | 71,267 | 356,335 | 621,041 | 3,105,205 | 4,347,287 | 21,736,435 |
| -1 | -5 | -7 | -35 | -61 | -305 | -427 | -2,135 | -10,181 | -50,905 | -71,267 | -356,335 | -621,041 | -3,105,205 | -4,347,287 | -21,736,435 |
