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 53,501,201, 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 | 53,501,201 | |
| -1 | -53,501,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,501,201.
Example:
1 x 53,501,201 = 53,501,201
and
-1 x -53,501,201 = 53,501,201
Notice both answers equal 53,501,201
With that explanation out of the way, let's continue. Next, we take the number 53,501,201 and divide it by 2:
53,501,201 ÷ 2 = 26,750,600.5
If the quotient is a whole number, then 2 and 26,750,600.5 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 | 53,501,201 | |
| -1 | -53,501,201 |
Now, we try dividing 53,501,201 by 3:
53,501,201 ÷ 3 = 17,833,733.6667
If the quotient is a whole number, then 3 and 17,833,733.6667 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 | 53,501,201 | |
| -1 | -53,501,201 |
Let's try dividing by 4:
53,501,201 ÷ 4 = 13,375,300.25
If the quotient is a whole number, then 4 and 13,375,300.25 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 | 53,501,201 | |
| -1 | 53,501,201 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 191 | 377 | 743 | 2,483 | 5,539 | 9,659 | 21,547 | 72,007 | 141,913 | 280,111 | 1,844,869 | 4,115,477 | 53,501,201 |
| -1 | -13 | -29 | -191 | -377 | -743 | -2,483 | -5,539 | -9,659 | -21,547 | -72,007 | -141,913 | -280,111 | -1,844,869 | -4,115,477 | -53,501,201 |
