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 51,205,525, 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 | 51,205,525 | |
| -1 | -51,205,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,205,525.
Example:
1 x 51,205,525 = 51,205,525
and
-1 x -51,205,525 = 51,205,525
Notice both answers equal 51,205,525
With that explanation out of the way, let's continue. Next, we take the number 51,205,525 and divide it by 2:
51,205,525 ÷ 2 = 25,602,762.5
If the quotient is a whole number, then 2 and 25,602,762.5 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 | 51,205,525 | |
| -1 | -51,205,525 |
Now, we try dividing 51,205,525 by 3:
51,205,525 ÷ 3 = 17,068,508.3333
If the quotient is a whole number, then 3 and 17,068,508.3333 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 | 51,205,525 | |
| -1 | -51,205,525 |
Let's try dividing by 4:
51,205,525 ÷ 4 = 12,801,381.25
If the quotient is a whole number, then 4 and 12,801,381.25 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 | 51,205,525 | |
| -1 | 51,205,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 227 | 1,135 | 1,289 | 1,589 | 5,675 | 6,445 | 7,945 | 9,023 | 32,225 | 39,725 | 45,115 | 225,575 | 292,603 | 1,463,015 | 2,048,221 | 7,315,075 | 10,241,105 | 51,205,525 |
| -1 | -5 | -7 | -25 | -35 | -175 | -227 | -1,135 | -1,289 | -1,589 | -5,675 | -6,445 | -7,945 | -9,023 | -32,225 | -39,725 | -45,115 | -225,575 | -292,603 | -1,463,015 | -2,048,221 | -7,315,075 | -10,241,105 | -51,205,525 |
