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 29,270,527, 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 | 29,270,527 | |
| -1 | -29,270,527 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 29,270,527.
Example:
1 x 29,270,527 = 29,270,527
and
-1 x -29,270,527 = 29,270,527
Notice both answers equal 29,270,527
With that explanation out of the way, let's continue. Next, we take the number 29,270,527 and divide it by 2:
29,270,527 ÷ 2 = 14,635,263.5
If the quotient is a whole number, then 2 and 14,635,263.5 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 | 29,270,527 | |
| -1 | -29,270,527 |
Now, we try dividing 29,270,527 by 3:
29,270,527 ÷ 3 = 9,756,842.3333
If the quotient is a whole number, then 3 and 9,756,842.3333 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 | 29,270,527 | |
| -1 | -29,270,527 |
Let's try dividing by 4:
29,270,527 ÷ 4 = 7,317,631.75
If the quotient is a whole number, then 4 and 7,317,631.75 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 | 29,270,527 | |
| -1 | 29,270,527 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 79 | 143 | 869 | 1,027 | 2,591 | 11,297 | 28,501 | 33,683 | 204,689 | 370,513 | 2,251,579 | 2,660,957 | 29,270,527 |
| -1 | -11 | -13 | -79 | -143 | -869 | -1,027 | -2,591 | -11,297 | -28,501 | -33,683 | -204,689 | -370,513 | -2,251,579 | -2,660,957 | -29,270,527 |
