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 7,202,425, 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 | 7,202,425 | |
| -1 | -7,202,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,202,425.
Example:
1 x 7,202,425 = 7,202,425
and
-1 x -7,202,425 = 7,202,425
Notice both answers equal 7,202,425
With that explanation out of the way, let's continue. Next, we take the number 7,202,425 and divide it by 2:
7,202,425 ÷ 2 = 3,601,212.5
If the quotient is a whole number, then 2 and 3,601,212.5 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 | 7,202,425 | |
| -1 | -7,202,425 |
Now, we try dividing 7,202,425 by 3:
7,202,425 ÷ 3 = 2,400,808.3333
If the quotient is a whole number, then 3 and 2,400,808.3333 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 | 7,202,425 | |
| -1 | -7,202,425 |
Let's try dividing by 4:
7,202,425 ÷ 4 = 1,800,606.25
If the quotient is a whole number, then 4 and 1,800,606.25 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 | 7,202,425 | |
| -1 | 7,202,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 59 | 95 | 257 | 295 | 475 | 1,121 | 1,285 | 1,475 | 4,883 | 5,605 | 6,425 | 15,163 | 24,415 | 28,025 | 75,815 | 122,075 | 288,097 | 379,075 | 1,440,485 | 7,202,425 |
| -1 | -5 | -19 | -25 | -59 | -95 | -257 | -295 | -475 | -1,121 | -1,285 | -1,475 | -4,883 | -5,605 | -6,425 | -15,163 | -24,415 | -28,025 | -75,815 | -122,075 | -288,097 | -379,075 | -1,440,485 | -7,202,425 |
