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 51,623,525, 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 | 51,623,525 | |
| -1 | -51,623,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,623,525.
Example:
1 x 51,623,525 = 51,623,525
and
-1 x -51,623,525 = 51,623,525
Notice both answers equal 51,623,525
With that explanation out of the way, let's continue. Next, we take the number 51,623,525 and divide it by 2:
51,623,525 ÷ 2 = 25,811,762.5
If the quotient is a whole number, then 2 and 25,811,762.5 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 | 51,623,525 | |
| -1 | -51,623,525 |
Now, we try dividing 51,623,525 by 3:
51,623,525 ÷ 3 = 17,207,841.6667
If the quotient is a whole number, then 3 and 17,207,841.6667 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 | 51,623,525 | |
| -1 | -51,623,525 |
Let's try dividing by 4:
51,623,525 ÷ 4 = 12,905,881.25
If the quotient is a whole number, then 4 and 12,905,881.25 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 | 51,623,525 | |
| -1 | 51,623,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 59 | 155 | 295 | 775 | 1,129 | 1,475 | 1,829 | 5,645 | 9,145 | 28,225 | 34,999 | 45,725 | 66,611 | 174,995 | 333,055 | 874,975 | 1,665,275 | 2,064,941 | 10,324,705 | 51,623,525 |
| -1 | -5 | -25 | -31 | -59 | -155 | -295 | -775 | -1,129 | -1,475 | -1,829 | -5,645 | -9,145 | -28,225 | -34,999 | -45,725 | -66,611 | -174,995 | -333,055 | -874,975 | -1,665,275 | -2,064,941 | -10,324,705 | -51,623,525 |
