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 51,738,575, 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 | 51,738,575 | |
| -1 | -51,738,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,738,575.
Example:
1 x 51,738,575 = 51,738,575
and
-1 x -51,738,575 = 51,738,575
Notice both answers equal 51,738,575
With that explanation out of the way, let's continue. Next, we take the number 51,738,575 and divide it by 2:
51,738,575 ÷ 2 = 25,869,287.5
If the quotient is a whole number, then 2 and 25,869,287.5 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 | 51,738,575 | |
| -1 | -51,738,575 |
Now, we try dividing 51,738,575 by 3:
51,738,575 ÷ 3 = 17,246,191.6667
If the quotient is a whole number, then 3 and 17,246,191.6667 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 | 51,738,575 | |
| -1 | -51,738,575 |
Let's try dividing by 4:
51,738,575 ÷ 4 = 12,934,643.75
If the quotient is a whole number, then 4 and 12,934,643.75 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 | 51,738,575 | |
| -1 | 51,738,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 59 | 175 | 295 | 413 | 1,475 | 2,065 | 5,011 | 10,325 | 25,055 | 35,077 | 125,275 | 175,385 | 295,649 | 876,925 | 1,478,245 | 2,069,543 | 7,391,225 | 10,347,715 | 51,738,575 |
| -1 | -5 | -7 | -25 | -35 | -59 | -175 | -295 | -413 | -1,475 | -2,065 | -5,011 | -10,325 | -25,055 | -35,077 | -125,275 | -175,385 | -295,649 | -876,925 | -1,478,245 | -2,069,543 | -7,391,225 | -10,347,715 | -51,738,575 |
