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 26,643,145, 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 | 26,643,145 | |
| -1 | -26,643,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,643,145.
Example:
1 x 26,643,145 = 26,643,145
and
-1 x -26,643,145 = 26,643,145
Notice both answers equal 26,643,145
With that explanation out of the way, let's continue. Next, we take the number 26,643,145 and divide it by 2:
26,643,145 ÷ 2 = 13,321,572.5
If the quotient is a whole number, then 2 and 13,321,572.5 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 | 26,643,145 | |
| -1 | -26,643,145 |
Now, we try dividing 26,643,145 by 3:
26,643,145 ÷ 3 = 8,881,048.3333
If the quotient is a whole number, then 3 and 8,881,048.3333 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 | 26,643,145 | |
| -1 | -26,643,145 |
Let's try dividing by 4:
26,643,145 ÷ 4 = 6,660,786.25
If the quotient is a whole number, then 4 and 6,660,786.25 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 | 26,643,145 | |
| -1 | 26,643,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 79 | 185 | 395 | 1,823 | 2,923 | 9,115 | 14,615 | 67,451 | 144,017 | 337,255 | 720,085 | 5,328,629 | 26,643,145 |
| -1 | -5 | -37 | -79 | -185 | -395 | -1,823 | -2,923 | -9,115 | -14,615 | -67,451 | -144,017 | -337,255 | -720,085 | -5,328,629 | -26,643,145 |
