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 51,502,675, 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 | 51,502,675 | |
| -1 | -51,502,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,502,675.
Example:
1 x 51,502,675 = 51,502,675
and
-1 x -51,502,675 = 51,502,675
Notice both answers equal 51,502,675
With that explanation out of the way, let's continue. Next, we take the number 51,502,675 and divide it by 2:
51,502,675 ÷ 2 = 25,751,337.5
If the quotient is a whole number, then 2 and 25,751,337.5 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 | 51,502,675 | |
| -1 | -51,502,675 |
Now, we try dividing 51,502,675 by 3:
51,502,675 ÷ 3 = 17,167,558.3333
If the quotient is a whole number, then 3 and 17,167,558.3333 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 | 51,502,675 | |
| -1 | -51,502,675 |
Let's try dividing by 4:
51,502,675 ÷ 4 = 12,875,668.75
If the quotient is a whole number, then 4 and 12,875,668.75 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 | 51,502,675 | |
| -1 | 51,502,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 42,043 | 210,215 | 294,301 | 1,051,075 | 1,471,505 | 2,060,107 | 7,357,525 | 10,300,535 | 51,502,675 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -42,043 | -210,215 | -294,301 | -1,051,075 | -1,471,505 | -2,060,107 | -7,357,525 | -10,300,535 | -51,502,675 |
