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 5,012,275, 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 | 5,012,275 | |
| -1 | -5,012,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,012,275.
Example:
1 x 5,012,275 = 5,012,275
and
-1 x -5,012,275 = 5,012,275
Notice both answers equal 5,012,275
With that explanation out of the way, let's continue. Next, we take the number 5,012,275 and divide it by 2:
5,012,275 ÷ 2 = 2,506,137.5
If the quotient is a whole number, then 2 and 2,506,137.5 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 | 5,012,275 | |
| -1 | -5,012,275 |
Now, we try dividing 5,012,275 by 3:
5,012,275 ÷ 3 = 1,670,758.3333
If the quotient is a whole number, then 3 and 1,670,758.3333 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 | 5,012,275 | |
| -1 | -5,012,275 |
Let's try dividing by 4:
5,012,275 ÷ 4 = 1,253,068.75
If the quotient is a whole number, then 4 and 1,253,068.75 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 | 5,012,275 | |
| -1 | 5,012,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 379 | 529 | 575 | 1,895 | 2,645 | 8,717 | 9,475 | 13,225 | 43,585 | 200,491 | 217,925 | 1,002,455 | 5,012,275 |
| -1 | -5 | -23 | -25 | -115 | -379 | -529 | -575 | -1,895 | -2,645 | -8,717 | -9,475 | -13,225 | -43,585 | -200,491 | -217,925 | -1,002,455 | -5,012,275 |
