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 53,183,615, 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 | 53,183,615 | |
| -1 | -53,183,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,183,615.
Example:
1 x 53,183,615 = 53,183,615
and
-1 x -53,183,615 = 53,183,615
Notice both answers equal 53,183,615
With that explanation out of the way, let's continue. Next, we take the number 53,183,615 and divide it by 2:
53,183,615 ÷ 2 = 26,591,807.5
If the quotient is a whole number, then 2 and 26,591,807.5 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 | 53,183,615 | |
| -1 | -53,183,615 |
Now, we try dividing 53,183,615 by 3:
53,183,615 ÷ 3 = 17,727,871.6667
If the quotient is a whole number, then 3 and 17,727,871.6667 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 | 53,183,615 | |
| -1 | -53,183,615 |
Let's try dividing by 4:
53,183,615 ÷ 4 = 13,295,903.75
If the quotient is a whole number, then 4 and 13,295,903.75 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 | 53,183,615 | |
| -1 | 53,183,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 71 | 185 | 355 | 2,627 | 4,049 | 13,135 | 20,245 | 149,813 | 287,479 | 749,065 | 1,437,395 | 10,636,723 | 53,183,615 |
| -1 | -5 | -37 | -71 | -185 | -355 | -2,627 | -4,049 | -13,135 | -20,245 | -149,813 | -287,479 | -749,065 | -1,437,395 | -10,636,723 | -53,183,615 |
