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 7,421,095, 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 | 7,421,095 | |
| -1 | -7,421,095 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,421,095.
Example:
1 x 7,421,095 = 7,421,095
and
-1 x -7,421,095 = 7,421,095
Notice both answers equal 7,421,095
With that explanation out of the way, let's continue. Next, we take the number 7,421,095 and divide it by 2:
7,421,095 ÷ 2 = 3,710,547.5
If the quotient is a whole number, then 2 and 3,710,547.5 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 | 7,421,095 | |
| -1 | -7,421,095 |
Now, we try dividing 7,421,095 by 3:
7,421,095 ÷ 3 = 2,473,698.3333
If the quotient is a whole number, then 3 and 2,473,698.3333 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 | 7,421,095 | |
| -1 | -7,421,095 |
Let's try dividing by 4:
7,421,095 ÷ 4 = 1,855,273.75
If the quotient is a whole number, then 4 and 1,855,273.75 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 | 7,421,095 | |
| -1 | 7,421,095 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 7,937 | 39,685 | 87,307 | 134,929 | 436,535 | 674,645 | 1,484,219 | 7,421,095 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -7,937 | -39,685 | -87,307 | -134,929 | -436,535 | -674,645 | -1,484,219 | -7,421,095 |
