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 15,366,175, 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 | 15,366,175 | |
| -1 | -15,366,175 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 15,366,175.
Example:
1 x 15,366,175 = 15,366,175
and
-1 x -15,366,175 = 15,366,175
Notice both answers equal 15,366,175
With that explanation out of the way, let's continue. Next, we take the number 15,366,175 and divide it by 2:
15,366,175 ÷ 2 = 7,683,087.5
If the quotient is a whole number, then 2 and 7,683,087.5 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 | 15,366,175 | |
| -1 | -15,366,175 |
Now, we try dividing 15,366,175 by 3:
15,366,175 ÷ 3 = 5,122,058.3333
If the quotient is a whole number, then 3 and 5,122,058.3333 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 | 15,366,175 | |
| -1 | -15,366,175 |
Let's try dividing by 4:
15,366,175 ÷ 4 = 3,841,543.75
If the quotient is a whole number, then 4 and 3,841,543.75 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 | 15,366,175 | |
| -1 | 15,366,175 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 71 | 275 | 355 | 781 | 787 | 1,775 | 3,905 | 3,935 | 8,657 | 19,525 | 19,675 | 43,285 | 55,877 | 216,425 | 279,385 | 614,647 | 1,396,925 | 3,073,235 | 15,366,175 |
| -1 | -5 | -11 | -25 | -55 | -71 | -275 | -355 | -781 | -787 | -1,775 | -3,905 | -3,935 | -8,657 | -19,525 | -19,675 | -43,285 | -55,877 | -216,425 | -279,385 | -614,647 | -1,396,925 | -3,073,235 | -15,366,175 |
