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 53,312,215, 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 | 53,312,215 | |
| -1 | -53,312,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,312,215.
Example:
1 x 53,312,215 = 53,312,215
and
-1 x -53,312,215 = 53,312,215
Notice both answers equal 53,312,215
With that explanation out of the way, let's continue. Next, we take the number 53,312,215 and divide it by 2:
53,312,215 ÷ 2 = 26,656,107.5
If the quotient is a whole number, then 2 and 26,656,107.5 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 | 53,312,215 | |
| -1 | -53,312,215 |
Now, we try dividing 53,312,215 by 3:
53,312,215 ÷ 3 = 17,770,738.3333
If the quotient is a whole number, then 3 and 17,770,738.3333 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 | 53,312,215 | |
| -1 | -53,312,215 |
Let's try dividing by 4:
53,312,215 ÷ 4 = 13,328,053.75
If the quotient is a whole number, then 4 and 13,328,053.75 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 | 53,312,215 | |
| -1 | 53,312,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 1,177 | 5,885 | 9,059 | 45,295 | 99,649 | 498,245 | 969,313 | 4,846,565 | 10,662,443 | 53,312,215 |
| -1 | -5 | -11 | -55 | -107 | -535 | -1,177 | -5,885 | -9,059 | -45,295 | -99,649 | -498,245 | -969,313 | -4,846,565 | -10,662,443 | -53,312,215 |
