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 10,361,615, 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 | 10,361,615 | |
| -1 | -10,361,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,361,615.
Example:
1 x 10,361,615 = 10,361,615
and
-1 x -10,361,615 = 10,361,615
Notice both answers equal 10,361,615
With that explanation out of the way, let's continue. Next, we take the number 10,361,615 and divide it by 2:
10,361,615 ÷ 2 = 5,180,807.5
If the quotient is a whole number, then 2 and 5,180,807.5 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 | 10,361,615 | |
| -1 | -10,361,615 |
Now, we try dividing 10,361,615 by 3:
10,361,615 ÷ 3 = 3,453,871.6667
If the quotient is a whole number, then 3 and 3,453,871.6667 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 | 10,361,615 | |
| -1 | -10,361,615 |
Let's try dividing by 4:
10,361,615 ÷ 4 = 2,590,403.75
If the quotient is a whole number, then 4 and 2,590,403.75 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 | 10,361,615 | |
| -1 | 10,361,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 55 | 115 | 253 | 1,265 | 8,191 | 40,955 | 90,101 | 188,393 | 450,505 | 941,965 | 2,072,323 | 10,361,615 |
| -1 | -5 | -11 | -23 | -55 | -115 | -253 | -1,265 | -8,191 | -40,955 | -90,101 | -188,393 | -450,505 | -941,965 | -2,072,323 | -10,361,615 |
