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 53,404,615, 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 | 53,404,615 | |
| -1 | -53,404,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,404,615.
Example:
1 x 53,404,615 = 53,404,615
and
-1 x -53,404,615 = 53,404,615
Notice both answers equal 53,404,615
With that explanation out of the way, let's continue. Next, we take the number 53,404,615 and divide it by 2:
53,404,615 ÷ 2 = 26,702,307.5
If the quotient is a whole number, then 2 and 26,702,307.5 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 | 53,404,615 | |
| -1 | -53,404,615 |
Now, we try dividing 53,404,615 by 3:
53,404,615 ÷ 3 = 17,801,538.3333
If the quotient is a whole number, then 3 and 17,801,538.3333 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 | 53,404,615 | |
| -1 | -53,404,615 |
Let's try dividing by 4:
53,404,615 ÷ 4 = 13,351,153.75
If the quotient is a whole number, then 4 and 13,351,153.75 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 | 53,404,615 | |
| -1 | 53,404,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 271 | 1,355 | 2,981 | 3,583 | 14,905 | 17,915 | 39,413 | 197,065 | 970,993 | 4,854,965 | 10,680,923 | 53,404,615 |
| -1 | -5 | -11 | -55 | -271 | -1,355 | -2,981 | -3,583 | -14,905 | -17,915 | -39,413 | -197,065 | -970,993 | -4,854,965 | -10,680,923 | -53,404,615 |
