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 13,274,611, 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 | 13,274,611 | |
| -1 | -13,274,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,274,611.
Example:
1 x 13,274,611 = 13,274,611
and
-1 x -13,274,611 = 13,274,611
Notice both answers equal 13,274,611
With that explanation out of the way, let's continue. Next, we take the number 13,274,611 and divide it by 2:
13,274,611 ÷ 2 = 6,637,305.5
If the quotient is a whole number, then 2 and 6,637,305.5 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 | 13,274,611 | |
| -1 | -13,274,611 |
Now, we try dividing 13,274,611 by 3:
13,274,611 ÷ 3 = 4,424,870.3333
If the quotient is a whole number, then 3 and 4,424,870.3333 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 | 13,274,611 | |
| -1 | -13,274,611 |
Let's try dividing by 4:
13,274,611 ÷ 4 = 3,318,652.75
If the quotient is a whole number, then 4 and 3,318,652.75 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 | 13,274,611 | |
| -1 | 13,274,611 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 41 | 161 | 287 | 943 | 2,011 | 6,601 | 14,077 | 46,253 | 82,451 | 323,771 | 577,157 | 1,896,373 | 13,274,611 |
| -1 | -7 | -23 | -41 | -161 | -287 | -943 | -2,011 | -6,601 | -14,077 | -46,253 | -82,451 | -323,771 | -577,157 | -1,896,373 | -13,274,611 |
