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 14,210,245, 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 | 14,210,245 | |
| -1 | -14,210,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,210,245.
Example:
1 x 14,210,245 = 14,210,245
and
-1 x -14,210,245 = 14,210,245
Notice both answers equal 14,210,245
With that explanation out of the way, let's continue. Next, we take the number 14,210,245 and divide it by 2:
14,210,245 ÷ 2 = 7,105,122.5
If the quotient is a whole number, then 2 and 7,105,122.5 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 | 14,210,245 | |
| -1 | -14,210,245 |
Now, we try dividing 14,210,245 by 3:
14,210,245 ÷ 3 = 4,736,748.3333
If the quotient is a whole number, then 3 and 4,736,748.3333 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 | 14,210,245 | |
| -1 | -14,210,245 |
Let's try dividing by 4:
14,210,245 ÷ 4 = 3,552,561.25
If the quotient is a whole number, then 4 and 3,552,561.25 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 | 14,210,245 | |
| -1 | 14,210,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 155 | 217 | 245 | 1,085 | 1,519 | 1,871 | 7,595 | 9,355 | 13,097 | 58,001 | 65,485 | 91,679 | 290,005 | 406,007 | 458,395 | 2,030,035 | 2,842,049 | 14,210,245 |
| -1 | -5 | -7 | -31 | -35 | -49 | -155 | -217 | -245 | -1,085 | -1,519 | -1,871 | -7,595 | -9,355 | -13,097 | -58,001 | -65,485 | -91,679 | -290,005 | -406,007 | -458,395 | -2,030,035 | -2,842,049 | -14,210,245 |
