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 315,152,425, 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 | 315,152,425 | |
| -1 | -315,152,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 315,152,425.
Example:
1 x 315,152,425 = 315,152,425
and
-1 x -315,152,425 = 315,152,425
Notice both answers equal 315,152,425
With that explanation out of the way, let's continue. Next, we take the number 315,152,425 and divide it by 2:
315,152,425 ÷ 2 = 157,576,212.5
If the quotient is a whole number, then 2 and 157,576,212.5 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 | 315,152,425 | |
| -1 | -315,152,425 |
Now, we try dividing 315,152,425 by 3:
315,152,425 ÷ 3 = 105,050,808.3333
If the quotient is a whole number, then 3 and 105,050,808.3333 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 | 315,152,425 | |
| -1 | -315,152,425 |
Let's try dividing by 4:
315,152,425 ÷ 4 = 78,788,106.25
If the quotient is a whole number, then 4 and 78,788,106.25 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 | 315,152,425 | |
| -1 | 315,152,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 145 | 175 | 203 | 725 | 1,015 | 5,075 | 62,099 | 310,495 | 434,693 | 1,552,475 | 1,800,871 | 2,173,465 | 9,004,355 | 10,867,325 | 12,606,097 | 45,021,775 | 63,030,485 | 315,152,425 |
| -1 | -5 | -7 | -25 | -29 | -35 | -145 | -175 | -203 | -725 | -1,015 | -5,075 | -62,099 | -310,495 | -434,693 | -1,552,475 | -1,800,871 | -2,173,465 | -9,004,355 | -10,867,325 | -12,606,097 | -45,021,775 | -63,030,485 | -315,152,425 |
