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 28,552,153, 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 | 28,552,153 | |
| -1 | -28,552,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,552,153.
Example:
1 x 28,552,153 = 28,552,153
and
-1 x -28,552,153 = 28,552,153
Notice both answers equal 28,552,153
With that explanation out of the way, let's continue. Next, we take the number 28,552,153 and divide it by 2:
28,552,153 ÷ 2 = 14,276,076.5
If the quotient is a whole number, then 2 and 14,276,076.5 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 | 28,552,153 | |
| -1 | -28,552,153 |
Now, we try dividing 28,552,153 by 3:
28,552,153 ÷ 3 = 9,517,384.3333
If the quotient is a whole number, then 3 and 9,517,384.3333 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 | 28,552,153 | |
| -1 | -28,552,153 |
Let's try dividing by 4:
28,552,153 ÷ 4 = 7,138,038.25
If the quotient is a whole number, then 4 and 7,138,038.25 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 | 28,552,153 | |
| -1 | 28,552,153 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 49 | 71 | 203 | 283 | 497 | 1,421 | 1,981 | 2,059 | 3,479 | 8,207 | 13,867 | 14,413 | 20,093 | 57,449 | 100,891 | 140,651 | 402,143 | 582,697 | 984,557 | 4,078,879 | 28,552,153 |
| -1 | -7 | -29 | -49 | -71 | -203 | -283 | -497 | -1,421 | -1,981 | -2,059 | -3,479 | -8,207 | -13,867 | -14,413 | -20,093 | -57,449 | -100,891 | -140,651 | -402,143 | -582,697 | -984,557 | -4,078,879 | -28,552,153 |
