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 2,210,425, 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 | 2,210,425 | |
| -1 | -2,210,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,210,425.
Example:
1 x 2,210,425 = 2,210,425
and
-1 x -2,210,425 = 2,210,425
Notice both answers equal 2,210,425
With that explanation out of the way, let's continue. Next, we take the number 2,210,425 and divide it by 2:
2,210,425 ÷ 2 = 1,105,212.5
If the quotient is a whole number, then 2 and 1,105,212.5 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 | 2,210,425 | |
| -1 | -2,210,425 |
Now, we try dividing 2,210,425 by 3:
2,210,425 ÷ 3 = 736,808.3333
If the quotient is a whole number, then 3 and 736,808.3333 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 | 2,210,425 | |
| -1 | -2,210,425 |
Let's try dividing by 4:
2,210,425 ÷ 4 = 552,606.25
If the quotient is a whole number, then 4 and 552,606.25 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 | 2,210,425 | |
| -1 | 2,210,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 85 | 119 | 175 | 425 | 595 | 743 | 2,975 | 3,715 | 5,201 | 12,631 | 18,575 | 26,005 | 63,155 | 88,417 | 130,025 | 315,775 | 442,085 | 2,210,425 |
| -1 | -5 | -7 | -17 | -25 | -35 | -85 | -119 | -175 | -425 | -595 | -743 | -2,975 | -3,715 | -5,201 | -12,631 | -18,575 | -26,005 | -63,155 | -88,417 | -130,025 | -315,775 | -442,085 | -2,210,425 |
