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 4,279,919, 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 | 4,279,919 | |
| -1 | -4,279,919 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,279,919.
Example:
1 x 4,279,919 = 4,279,919
and
-1 x -4,279,919 = 4,279,919
Notice both answers equal 4,279,919
With that explanation out of the way, let's continue. Next, we take the number 4,279,919 and divide it by 2:
4,279,919 ÷ 2 = 2,139,959.5
If the quotient is a whole number, then 2 and 2,139,959.5 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 | 4,279,919 | |
| -1 | -4,279,919 |
Now, we try dividing 4,279,919 by 3:
4,279,919 ÷ 3 = 1,426,639.6667
If the quotient is a whole number, then 3 and 1,426,639.6667 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 | 4,279,919 | |
| -1 | -4,279,919 |
Let's try dividing by 4:
4,279,919 ÷ 4 = 1,069,979.75
If the quotient is a whole number, then 4 and 1,069,979.75 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 | 4,279,919 | |
| -1 | 4,279,919 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 59 | 241 | 301 | 413 | 1,687 | 2,537 | 10,363 | 14,219 | 17,759 | 72,541 | 99,533 | 611,417 | 4,279,919 |
| -1 | -7 | -43 | -59 | -241 | -301 | -413 | -1,687 | -2,537 | -10,363 | -14,219 | -17,759 | -72,541 | -99,533 | -611,417 | -4,279,919 |
