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 6,920,221, 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 | 6,920,221 | |
| -1 | -6,920,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,920,221.
Example:
1 x 6,920,221 = 6,920,221
and
-1 x -6,920,221 = 6,920,221
Notice both answers equal 6,920,221
With that explanation out of the way, let's continue. Next, we take the number 6,920,221 and divide it by 2:
6,920,221 ÷ 2 = 3,460,110.5
If the quotient is a whole number, then 2 and 3,460,110.5 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 | 6,920,221 | |
| -1 | -6,920,221 |
Now, we try dividing 6,920,221 by 3:
6,920,221 ÷ 3 = 2,306,740.3333
If the quotient is a whole number, then 3 and 2,306,740.3333 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 | 6,920,221 | |
| -1 | -6,920,221 |
Let's try dividing by 4:
6,920,221 ÷ 4 = 1,730,055.25
If the quotient is a whole number, then 4 and 1,730,055.25 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 | 6,920,221 | |
| -1 | 6,920,221 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 37 | 49 | 77 | 259 | 347 | 407 | 539 | 1,813 | 2,429 | 2,849 | 3,817 | 12,839 | 17,003 | 19,943 | 26,719 | 89,873 | 141,229 | 187,033 | 629,111 | 988,603 | 6,920,221 |
| -1 | -7 | -11 | -37 | -49 | -77 | -259 | -347 | -407 | -539 | -1,813 | -2,429 | -2,849 | -3,817 | -12,839 | -17,003 | -19,943 | -26,719 | -89,873 | -141,229 | -187,033 | -629,111 | -988,603 | -6,920,221 |
