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 27,038,725, 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 | 27,038,725 | |
| -1 | -27,038,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,038,725.
Example:
1 x 27,038,725 = 27,038,725
and
-1 x -27,038,725 = 27,038,725
Notice both answers equal 27,038,725
With that explanation out of the way, let's continue. Next, we take the number 27,038,725 and divide it by 2:
27,038,725 ÷ 2 = 13,519,362.5
If the quotient is a whole number, then 2 and 13,519,362.5 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 | 27,038,725 | |
| -1 | -27,038,725 |
Now, we try dividing 27,038,725 by 3:
27,038,725 ÷ 3 = 9,012,908.3333
If the quotient is a whole number, then 3 and 9,012,908.3333 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 | 27,038,725 | |
| -1 | -27,038,725 |
Let's try dividing by 4:
27,038,725 ÷ 4 = 6,759,681.25
If the quotient is a whole number, then 4 and 6,759,681.25 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 | 27,038,725 | |
| -1 | 27,038,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 367 | 421 | 1,835 | 2,105 | 2,569 | 2,947 | 9,175 | 10,525 | 12,845 | 14,735 | 64,225 | 73,675 | 154,507 | 772,535 | 1,081,549 | 3,862,675 | 5,407,745 | 27,038,725 |
| -1 | -5 | -7 | -25 | -35 | -175 | -367 | -421 | -1,835 | -2,105 | -2,569 | -2,947 | -9,175 | -10,525 | -12,845 | -14,735 | -64,225 | -73,675 | -154,507 | -772,535 | -1,081,549 | -3,862,675 | -5,407,745 | -27,038,725 |
