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 28,918,435, 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 | 28,918,435 | |
| -1 | -28,918,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,918,435.
Example:
1 x 28,918,435 = 28,918,435
and
-1 x -28,918,435 = 28,918,435
Notice both answers equal 28,918,435
With that explanation out of the way, let's continue. Next, we take the number 28,918,435 and divide it by 2:
28,918,435 ÷ 2 = 14,459,217.5
If the quotient is a whole number, then 2 and 14,459,217.5 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 | 28,918,435 | |
| -1 | -28,918,435 |
Now, we try dividing 28,918,435 by 3:
28,918,435 ÷ 3 = 9,639,478.3333
If the quotient is a whole number, then 3 and 9,639,478.3333 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 | 28,918,435 | |
| -1 | -28,918,435 |
Let's try dividing by 4:
28,918,435 ÷ 4 = 7,229,608.75
If the quotient is a whole number, then 4 and 7,229,608.75 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 | 28,918,435 | |
| -1 | 28,918,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 169 | 455 | 845 | 1,183 | 4,889 | 5,915 | 24,445 | 34,223 | 63,557 | 171,115 | 317,785 | 444,899 | 826,241 | 2,224,495 | 4,131,205 | 5,783,687 | 28,918,435 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -169 | -455 | -845 | -1,183 | -4,889 | -5,915 | -24,445 | -34,223 | -63,557 | -171,115 | -317,785 | -444,899 | -826,241 | -2,224,495 | -4,131,205 | -5,783,687 | -28,918,435 |
