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 50,551,615, 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 | 50,551,615 | |
| -1 | -50,551,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,551,615.
Example:
1 x 50,551,615 = 50,551,615
and
-1 x -50,551,615 = 50,551,615
Notice both answers equal 50,551,615
With that explanation out of the way, let's continue. Next, we take the number 50,551,615 and divide it by 2:
50,551,615 ÷ 2 = 25,275,807.5
If the quotient is a whole number, then 2 and 25,275,807.5 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 | 50,551,615 | |
| -1 | -50,551,615 |
Now, we try dividing 50,551,615 by 3:
50,551,615 ÷ 3 = 16,850,538.3333
If the quotient is a whole number, then 3 and 16,850,538.3333 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 | 50,551,615 | |
| -1 | -50,551,615 |
Let's try dividing by 4:
50,551,615 ÷ 4 = 12,637,903.75
If the quotient is a whole number, then 4 and 12,637,903.75 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 | 50,551,615 | |
| -1 | 50,551,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 107 | 305 | 535 | 1,549 | 6,527 | 7,745 | 32,635 | 94,489 | 165,743 | 472,445 | 828,715 | 10,110,323 | 50,551,615 |
| -1 | -5 | -61 | -107 | -305 | -535 | -1,549 | -6,527 | -7,745 | -32,635 | -94,489 | -165,743 | -472,445 | -828,715 | -10,110,323 | -50,551,615 |
