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 27,130,859, 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 | 27,130,859 | |
| -1 | -27,130,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,130,859.
Example:
1 x 27,130,859 = 27,130,859
and
-1 x -27,130,859 = 27,130,859
Notice both answers equal 27,130,859
With that explanation out of the way, let's continue. Next, we take the number 27,130,859 and divide it by 2:
27,130,859 ÷ 2 = 13,565,429.5
If the quotient is a whole number, then 2 and 13,565,429.5 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 | 27,130,859 | |
| -1 | -27,130,859 |
Now, we try dividing 27,130,859 by 3:
27,130,859 ÷ 3 = 9,043,619.6667
If the quotient is a whole number, then 3 and 9,043,619.6667 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 | 27,130,859 | |
| -1 | -27,130,859 |
Let's try dividing by 4:
27,130,859 ÷ 4 = 6,782,714.75
If the quotient is a whole number, then 4 and 6,782,714.75 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 | 27,130,859 | |
| -1 | 27,130,859 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 53 | 217 | 337 | 371 | 1,519 | 1,643 | 2,359 | 2,597 | 10,447 | 11,501 | 16,513 | 17,861 | 73,129 | 80,507 | 125,027 | 511,903 | 553,691 | 875,189 | 3,875,837 | 27,130,859 |
| -1 | -7 | -31 | -49 | -53 | -217 | -337 | -371 | -1,519 | -1,643 | -2,359 | -2,597 | -10,447 | -11,501 | -16,513 | -17,861 | -73,129 | -80,507 | -125,027 | -511,903 | -553,691 | -875,189 | -3,875,837 | -27,130,859 |
