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 28,875,833, 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 | 28,875,833 | |
| -1 | -28,875,833 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,875,833.
Example:
1 x 28,875,833 = 28,875,833
and
-1 x -28,875,833 = 28,875,833
Notice both answers equal 28,875,833
With that explanation out of the way, let's continue. Next, we take the number 28,875,833 and divide it by 2:
28,875,833 ÷ 2 = 14,437,916.5
If the quotient is a whole number, then 2 and 14,437,916.5 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 | 28,875,833 | |
| -1 | -28,875,833 |
Now, we try dividing 28,875,833 by 3:
28,875,833 ÷ 3 = 9,625,277.6667
If the quotient is a whole number, then 3 and 9,625,277.6667 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 | 28,875,833 | |
| -1 | -28,875,833 |
Let's try dividing by 4:
28,875,833 ÷ 4 = 7,218,958.25
If the quotient is a whole number, then 4 and 7,218,958.25 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 | 28,875,833 | |
| -1 | 28,875,833 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 97 | 161 | 301 | 679 | 989 | 1,849 | 2,231 | 4,171 | 6,923 | 12,943 | 15,617 | 29,197 | 42,527 | 95,933 | 179,353 | 297,689 | 671,531 | 1,255,471 | 4,125,119 | 28,875,833 |
| -1 | -7 | -23 | -43 | -97 | -161 | -301 | -679 | -989 | -1,849 | -2,231 | -4,171 | -6,923 | -12,943 | -15,617 | -29,197 | -42,527 | -95,933 | -179,353 | -297,689 | -671,531 | -1,255,471 | -4,125,119 | -28,875,833 |
