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 21,706,435, 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 | 21,706,435 | |
| -1 | -21,706,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,706,435.
Example:
1 x 21,706,435 = 21,706,435
and
-1 x -21,706,435 = 21,706,435
Notice both answers equal 21,706,435
With that explanation out of the way, let's continue. Next, we take the number 21,706,435 and divide it by 2:
21,706,435 ÷ 2 = 10,853,217.5
If the quotient is a whole number, then 2 and 10,853,217.5 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 | 21,706,435 | |
| -1 | -21,706,435 |
Now, we try dividing 21,706,435 by 3:
21,706,435 ÷ 3 = 7,235,478.3333
If the quotient is a whole number, then 3 and 7,235,478.3333 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 | 21,706,435 | |
| -1 | -21,706,435 |
Let's try dividing by 4:
21,706,435 ÷ 4 = 5,426,608.75
If the quotient is a whole number, then 4 and 5,426,608.75 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 | 21,706,435 | |
| -1 | 21,706,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 179 | 307 | 395 | 895 | 1,535 | 14,141 | 24,253 | 54,953 | 70,705 | 121,265 | 274,765 | 4,341,287 | 21,706,435 |
| -1 | -5 | -79 | -179 | -307 | -395 | -895 | -1,535 | -14,141 | -24,253 | -54,953 | -70,705 | -121,265 | -274,765 | -4,341,287 | -21,706,435 |
