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 26,894,875, 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 | 26,894,875 | |
| -1 | -26,894,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,894,875.
Example:
1 x 26,894,875 = 26,894,875
and
-1 x -26,894,875 = 26,894,875
Notice both answers equal 26,894,875
With that explanation out of the way, let's continue. Next, we take the number 26,894,875 and divide it by 2:
26,894,875 ÷ 2 = 13,447,437.5
If the quotient is a whole number, then 2 and 13,447,437.5 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 | 26,894,875 | |
| -1 | -26,894,875 |
Now, we try dividing 26,894,875 by 3:
26,894,875 ÷ 3 = 8,964,958.3333
If the quotient is a whole number, then 3 and 8,964,958.3333 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 | 26,894,875 | |
| -1 | -26,894,875 |
Let's try dividing by 4:
26,894,875 ÷ 4 = 6,723,718.75
If the quotient is a whole number, then 4 and 6,723,718.75 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 | 26,894,875 | |
| -1 | 26,894,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 125 | 175 | 245 | 875 | 1,225 | 4,391 | 6,125 | 21,955 | 30,737 | 109,775 | 153,685 | 215,159 | 548,875 | 768,425 | 1,075,795 | 3,842,125 | 5,378,975 | 26,894,875 |
| -1 | -5 | -7 | -25 | -35 | -49 | -125 | -175 | -245 | -875 | -1,225 | -4,391 | -6,125 | -21,955 | -30,737 | -109,775 | -153,685 | -215,159 | -548,875 | -768,425 | -1,075,795 | -3,842,125 | -5,378,975 | -26,894,875 |
