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 27,472,487, 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 | 27,472,487 | |
| -1 | -27,472,487 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,472,487.
Example:
1 x 27,472,487 = 27,472,487
and
-1 x -27,472,487 = 27,472,487
Notice both answers equal 27,472,487
With that explanation out of the way, let's continue. Next, we take the number 27,472,487 and divide it by 2:
27,472,487 ÷ 2 = 13,736,243.5
If the quotient is a whole number, then 2 and 13,736,243.5 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 | 27,472,487 | |
| -1 | -27,472,487 |
Now, we try dividing 27,472,487 by 3:
27,472,487 ÷ 3 = 9,157,495.6667
If the quotient is a whole number, then 3 and 9,157,495.6667 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 | 27,472,487 | |
| -1 | -27,472,487 |
Let's try dividing by 4:
27,472,487 ÷ 4 = 6,868,121.75
If the quotient is a whole number, then 4 and 6,868,121.75 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 | 27,472,487 | |
| -1 | 27,472,487 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 49 | 79 | 151 | 329 | 553 | 1,057 | 2,303 | 3,713 | 3,871 | 7,097 | 7,399 | 11,929 | 25,991 | 49,679 | 83,503 | 181,937 | 347,753 | 560,663 | 584,521 | 3,924,641 | 27,472,487 |
| -1 | -7 | -47 | -49 | -79 | -151 | -329 | -553 | -1,057 | -2,303 | -3,713 | -3,871 | -7,097 | -7,399 | -11,929 | -25,991 | -49,679 | -83,503 | -181,937 | -347,753 | -560,663 | -584,521 | -3,924,641 | -27,472,487 |
