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 53,306,437, 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 | 53,306,437 | |
| -1 | -53,306,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,306,437.
Example:
1 x 53,306,437 = 53,306,437
and
-1 x -53,306,437 = 53,306,437
Notice both answers equal 53,306,437
With that explanation out of the way, let's continue. Next, we take the number 53,306,437 and divide it by 2:
53,306,437 ÷ 2 = 26,653,218.5
If the quotient is a whole number, then 2 and 26,653,218.5 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 | 53,306,437 | |
| -1 | -53,306,437 |
Now, we try dividing 53,306,437 by 3:
53,306,437 ÷ 3 = 17,768,812.3333
If the quotient is a whole number, then 3 and 17,768,812.3333 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 | 53,306,437 | |
| -1 | -53,306,437 |
Let's try dividing by 4:
53,306,437 ÷ 4 = 13,326,609.25
If the quotient is a whole number, then 4 and 13,326,609.25 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 | 53,306,437 | |
| -1 | 53,306,437 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 107 | 419 | 1,189 | 3,103 | 4,387 | 12,151 | 17,179 | 44,833 | 127,223 | 498,191 | 1,300,157 | 1,838,153 | 53,306,437 |
| -1 | -29 | -41 | -107 | -419 | -1,189 | -3,103 | -4,387 | -12,151 | -17,179 | -44,833 | -127,223 | -498,191 | -1,300,157 | -1,838,153 | -53,306,437 |
