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 7,701,211, 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 | 7,701,211 | |
| -1 | -7,701,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,701,211.
Example:
1 x 7,701,211 = 7,701,211
and
-1 x -7,701,211 = 7,701,211
Notice both answers equal 7,701,211
With that explanation out of the way, let's continue. Next, we take the number 7,701,211 and divide it by 2:
7,701,211 ÷ 2 = 3,850,605.5
If the quotient is a whole number, then 2 and 3,850,605.5 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 | 7,701,211 | |
| -1 | -7,701,211 |
Now, we try dividing 7,701,211 by 3:
7,701,211 ÷ 3 = 2,567,070.3333
If the quotient is a whole number, then 3 and 2,567,070.3333 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 | 7,701,211 | |
| -1 | -7,701,211 |
Let's try dividing by 4:
7,701,211 ÷ 4 = 1,925,302.75
If the quotient is a whole number, then 4 and 1,925,302.75 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 | 7,701,211 | |
| -1 | 7,701,211 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 59 | 203 | 413 | 643 | 1,711 | 4,501 | 11,977 | 18,647 | 37,937 | 130,529 | 265,559 | 1,100,173 | 7,701,211 |
| -1 | -7 | -29 | -59 | -203 | -413 | -643 | -1,711 | -4,501 | -11,977 | -18,647 | -37,937 | -130,529 | -265,559 | -1,100,173 | -7,701,211 |
