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 53,235,415, 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 | 53,235,415 | |
| -1 | -53,235,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,235,415.
Example:
1 x 53,235,415 = 53,235,415
and
-1 x -53,235,415 = 53,235,415
Notice both answers equal 53,235,415
With that explanation out of the way, let's continue. Next, we take the number 53,235,415 and divide it by 2:
53,235,415 ÷ 2 = 26,617,707.5
If the quotient is a whole number, then 2 and 26,617,707.5 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 | 53,235,415 | |
| -1 | -53,235,415 |
Now, we try dividing 53,235,415 by 3:
53,235,415 ÷ 3 = 17,745,138.3333
If the quotient is a whole number, then 3 and 17,745,138.3333 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 | 53,235,415 | |
| -1 | -53,235,415 |
Let's try dividing by 4:
53,235,415 ÷ 4 = 13,308,853.75
If the quotient is a whole number, then 4 and 13,308,853.75 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 | 53,235,415 | |
| -1 | 53,235,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 16,927 | 84,635 | 287,759 | 626,299 | 1,438,795 | 3,131,495 | 10,647,083 | 53,235,415 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -16,927 | -84,635 | -287,759 | -626,299 | -1,438,795 | -3,131,495 | -10,647,083 | -53,235,415 |
