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 6,190,219, 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 | 6,190,219 | |
| -1 | -6,190,219 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,190,219.
Example:
1 x 6,190,219 = 6,190,219
and
-1 x -6,190,219 = 6,190,219
Notice both answers equal 6,190,219
With that explanation out of the way, let's continue. Next, we take the number 6,190,219 and divide it by 2:
6,190,219 ÷ 2 = 3,095,109.5
If the quotient is a whole number, then 2 and 3,095,109.5 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 | 6,190,219 | |
| -1 | -6,190,219 |
Now, we try dividing 6,190,219 by 3:
6,190,219 ÷ 3 = 2,063,406.3333
If the quotient is a whole number, then 3 and 2,063,406.3333 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 | 6,190,219 | |
| -1 | -6,190,219 |
Let's try dividing by 4:
6,190,219 ÷ 4 = 1,547,554.75
If the quotient is a whole number, then 4 and 1,547,554.75 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 | 6,190,219 | |
| -1 | 6,190,219 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 61 | 109 | 133 | 427 | 763 | 931 | 1,159 | 2,071 | 2,989 | 5,341 | 6,649 | 8,113 | 14,497 | 46,543 | 56,791 | 101,479 | 126,331 | 325,801 | 884,317 | 6,190,219 |
| -1 | -7 | -19 | -49 | -61 | -109 | -133 | -427 | -763 | -931 | -1,159 | -2,071 | -2,989 | -5,341 | -6,649 | -8,113 | -14,497 | -46,543 | -56,791 | -101,479 | -126,331 | -325,801 | -884,317 | -6,190,219 |
