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 30,152,425, 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 | 30,152,425 | |
| -1 | -30,152,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,152,425.
Example:
1 x 30,152,425 = 30,152,425
and
-1 x -30,152,425 = 30,152,425
Notice both answers equal 30,152,425
With that explanation out of the way, let's continue. Next, we take the number 30,152,425 and divide it by 2:
30,152,425 ÷ 2 = 15,076,212.5
If the quotient is a whole number, then 2 and 15,076,212.5 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 | 30,152,425 | |
| -1 | -30,152,425 |
Now, we try dividing 30,152,425 by 3:
30,152,425 ÷ 3 = 10,050,808.3333
If the quotient is a whole number, then 3 and 10,050,808.3333 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 | 30,152,425 | |
| -1 | -30,152,425 |
Let's try dividing by 4:
30,152,425 ÷ 4 = 7,538,106.25
If the quotient is a whole number, then 4 and 7,538,106.25 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 | 30,152,425 | |
| -1 | 30,152,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 41 | 115 | 205 | 575 | 943 | 1,025 | 1,279 | 4,715 | 6,395 | 23,575 | 29,417 | 31,975 | 52,439 | 147,085 | 262,195 | 735,425 | 1,206,097 | 1,310,975 | 6,030,485 | 30,152,425 |
| -1 | -5 | -23 | -25 | -41 | -115 | -205 | -575 | -943 | -1,025 | -1,279 | -4,715 | -6,395 | -23,575 | -29,417 | -31,975 | -52,439 | -147,085 | -262,195 | -735,425 | -1,206,097 | -1,310,975 | -6,030,485 | -30,152,425 |
