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 10,874,275, 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 | 10,874,275 | |
| -1 | -10,874,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,874,275.
Example:
1 x 10,874,275 = 10,874,275
and
-1 x -10,874,275 = 10,874,275
Notice both answers equal 10,874,275
With that explanation out of the way, let's continue. Next, we take the number 10,874,275 and divide it by 2:
10,874,275 ÷ 2 = 5,437,137.5
If the quotient is a whole number, then 2 and 5,437,137.5 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 | 10,874,275 | |
| -1 | -10,874,275 |
Now, we try dividing 10,874,275 by 3:
10,874,275 ÷ 3 = 3,624,758.3333
If the quotient is a whole number, then 3 and 3,624,758.3333 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 | 10,874,275 | |
| -1 | -10,874,275 |
Let's try dividing by 4:
10,874,275 ÷ 4 = 2,718,568.75
If the quotient is a whole number, then 4 and 2,718,568.75 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 | 10,874,275 | |
| -1 | 10,874,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 53 | 145 | 265 | 283 | 725 | 1,325 | 1,415 | 1,537 | 7,075 | 7,685 | 8,207 | 14,999 | 38,425 | 41,035 | 74,995 | 205,175 | 374,975 | 434,971 | 2,174,855 | 10,874,275 |
| -1 | -5 | -25 | -29 | -53 | -145 | -265 | -283 | -725 | -1,325 | -1,415 | -1,537 | -7,075 | -7,685 | -8,207 | -14,999 | -38,425 | -41,035 | -74,995 | -205,175 | -374,975 | -434,971 | -2,174,855 | -10,874,275 |
