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 4,668,391, 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 | 4,668,391 | |
| -1 | -4,668,391 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,668,391.
Example:
1 x 4,668,391 = 4,668,391
and
-1 x -4,668,391 = 4,668,391
Notice both answers equal 4,668,391
With that explanation out of the way, let's continue. Next, we take the number 4,668,391 and divide it by 2:
4,668,391 ÷ 2 = 2,334,195.5
If the quotient is a whole number, then 2 and 2,334,195.5 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 | 4,668,391 | |
| -1 | -4,668,391 |
Now, we try dividing 4,668,391 by 3:
4,668,391 ÷ 3 = 1,556,130.3333
If the quotient is a whole number, then 3 and 1,556,130.3333 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 | 4,668,391 | |
| -1 | -4,668,391 |
Let's try dividing by 4:
4,668,391 ÷ 4 = 1,167,097.75
If the quotient is a whole number, then 4 and 1,167,097.75 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 | 4,668,391 | |
| -1 | 4,668,391 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 61 | 91 | 203 | 377 | 427 | 793 | 841 | 1,769 | 2,639 | 5,551 | 5,887 | 10,933 | 12,383 | 22,997 | 51,301 | 76,531 | 160,979 | 359,107 | 666,913 | 4,668,391 |
| -1 | -7 | -13 | -29 | -61 | -91 | -203 | -377 | -427 | -793 | -841 | -1,769 | -2,639 | -5,551 | -5,887 | -10,933 | -12,383 | -22,997 | -51,301 | -76,531 | -160,979 | -359,107 | -666,913 | -4,668,391 |
