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 53,016,251, 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 | 53,016,251 | |
| -1 | -53,016,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,016,251.
Example:
1 x 53,016,251 = 53,016,251
and
-1 x -53,016,251 = 53,016,251
Notice both answers equal 53,016,251
With that explanation out of the way, let's continue. Next, we take the number 53,016,251 and divide it by 2:
53,016,251 ÷ 2 = 26,508,125.5
If the quotient is a whole number, then 2 and 26,508,125.5 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 | 53,016,251 | |
| -1 | -53,016,251 |
Now, we try dividing 53,016,251 by 3:
53,016,251 ÷ 3 = 17,672,083.6667
If the quotient is a whole number, then 3 and 17,672,083.6667 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 | 53,016,251 | |
| -1 | -53,016,251 |
Let's try dividing by 4:
53,016,251 ÷ 4 = 13,254,062.75
If the quotient is a whole number, then 4 and 13,254,062.75 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 | 53,016,251 | |
| -1 | 53,016,251 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 151 | 323 | 1,087 | 2,567 | 2,869 | 18,479 | 20,653 | 48,773 | 164,137 | 351,101 | 2,790,329 | 3,118,603 | 53,016,251 |
| -1 | -17 | -19 | -151 | -323 | -1,087 | -2,567 | -2,869 | -18,479 | -20,653 | -48,773 | -164,137 | -351,101 | -2,790,329 | -3,118,603 | -53,016,251 |
