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 65,424,425, 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 | 65,424,425 | |
| -1 | -65,424,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 65,424,425.
Example:
1 x 65,424,425 = 65,424,425
and
-1 x -65,424,425 = 65,424,425
Notice both answers equal 65,424,425
With that explanation out of the way, let's continue. Next, we take the number 65,424,425 and divide it by 2:
65,424,425 ÷ 2 = 32,712,212.5
If the quotient is a whole number, then 2 and 32,712,212.5 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 | 65,424,425 | |
| -1 | -65,424,425 |
Now, we try dividing 65,424,425 by 3:
65,424,425 ÷ 3 = 21,808,141.6667
If the quotient is a whole number, then 3 and 21,808,141.6667 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 | 65,424,425 | |
| -1 | -65,424,425 |
Let's try dividing by 4:
65,424,425 ÷ 4 = 16,356,106.25
If the quotient is a whole number, then 4 and 16,356,106.25 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 | 65,424,425 | |
| -1 | 65,424,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 73 | 275 | 365 | 803 | 1,825 | 3,259 | 4,015 | 16,295 | 20,075 | 35,849 | 81,475 | 179,245 | 237,907 | 896,225 | 1,189,535 | 2,616,977 | 5,947,675 | 13,084,885 | 65,424,425 |
| -1 | -5 | -11 | -25 | -55 | -73 | -275 | -365 | -803 | -1,825 | -3,259 | -4,015 | -16,295 | -20,075 | -35,849 | -81,475 | -179,245 | -237,907 | -896,225 | -1,189,535 | -2,616,977 | -5,947,675 | -13,084,885 | -65,424,425 |
