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 10,216,675, 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 | 10,216,675 | |
| -1 | -10,216,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,216,675.
Example:
1 x 10,216,675 = 10,216,675
and
-1 x -10,216,675 = 10,216,675
Notice both answers equal 10,216,675
With that explanation out of the way, let's continue. Next, we take the number 10,216,675 and divide it by 2:
10,216,675 ÷ 2 = 5,108,337.5
If the quotient is a whole number, then 2 and 5,108,337.5 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 | 10,216,675 | |
| -1 | -10,216,675 |
Now, we try dividing 10,216,675 by 3:
10,216,675 ÷ 3 = 3,405,558.3333
If the quotient is a whole number, then 3 and 3,405,558.3333 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 | 10,216,675 | |
| -1 | -10,216,675 |
Let's try dividing by 4:
10,216,675 ÷ 4 = 2,554,168.75
If the quotient is a whole number, then 4 and 2,554,168.75 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 | 10,216,675 | |
| -1 | 10,216,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 79 | 175 | 395 | 553 | 739 | 1,975 | 2,765 | 3,695 | 5,173 | 13,825 | 18,475 | 25,865 | 58,381 | 129,325 | 291,905 | 408,667 | 1,459,525 | 2,043,335 | 10,216,675 |
| -1 | -5 | -7 | -25 | -35 | -79 | -175 | -395 | -553 | -739 | -1,975 | -2,765 | -3,695 | -5,173 | -13,825 | -18,475 | -25,865 | -58,381 | -129,325 | -291,905 | -408,667 | -1,459,525 | -2,043,335 | -10,216,675 |
