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 7,974,275, 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 | 7,974,275 | |
| -1 | -7,974,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,974,275.
Example:
1 x 7,974,275 = 7,974,275
and
-1 x -7,974,275 = 7,974,275
Notice both answers equal 7,974,275
With that explanation out of the way, let's continue. Next, we take the number 7,974,275 and divide it by 2:
7,974,275 ÷ 2 = 3,987,137.5
If the quotient is a whole number, then 2 and 3,987,137.5 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 | 7,974,275 | |
| -1 | -7,974,275 |
Now, we try dividing 7,974,275 by 3:
7,974,275 ÷ 3 = 2,658,091.6667
If the quotient is a whole number, then 3 and 2,658,091.6667 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 | 7,974,275 | |
| -1 | -7,974,275 |
Let's try dividing by 4:
7,974,275 ÷ 4 = 1,993,568.75
If the quotient is a whole number, then 4 and 1,993,568.75 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 | 7,974,275 | |
| -1 | 7,974,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 29 | 85 | 145 | 425 | 493 | 647 | 725 | 2,465 | 3,235 | 10,999 | 12,325 | 16,175 | 18,763 | 54,995 | 93,815 | 274,975 | 318,971 | 469,075 | 1,594,855 | 7,974,275 |
| -1 | -5 | -17 | -25 | -29 | -85 | -145 | -425 | -493 | -647 | -725 | -2,465 | -3,235 | -10,999 | -12,325 | -16,175 | -18,763 | -54,995 | -93,815 | -274,975 | -318,971 | -469,075 | -1,594,855 | -7,974,275 |
