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 55,250,425, 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 | 55,250,425 | |
| -1 | -55,250,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,250,425.
Example:
1 x 55,250,425 = 55,250,425
and
-1 x -55,250,425 = 55,250,425
Notice both answers equal 55,250,425
With that explanation out of the way, let's continue. Next, we take the number 55,250,425 and divide it by 2:
55,250,425 ÷ 2 = 27,625,212.5
If the quotient is a whole number, then 2 and 27,625,212.5 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 | 55,250,425 | |
| -1 | -55,250,425 |
Now, we try dividing 55,250,425 by 3:
55,250,425 ÷ 3 = 18,416,808.3333
If the quotient is a whole number, then 3 and 18,416,808.3333 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 | 55,250,425 | |
| -1 | -55,250,425 |
Let's try dividing by 4:
55,250,425 ÷ 4 = 13,812,606.25
If the quotient is a whole number, then 4 and 13,812,606.25 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 | 55,250,425 | |
| -1 | 55,250,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 71 | 85 | 355 | 425 | 1,207 | 1,775 | 1,831 | 6,035 | 9,155 | 30,175 | 31,127 | 45,775 | 130,001 | 155,635 | 650,005 | 778,175 | 2,210,017 | 3,250,025 | 11,050,085 | 55,250,425 |
| -1 | -5 | -17 | -25 | -71 | -85 | -355 | -425 | -1,207 | -1,775 | -1,831 | -6,035 | -9,155 | -30,175 | -31,127 | -45,775 | -130,001 | -155,635 | -650,005 | -778,175 | -2,210,017 | -3,250,025 | -11,050,085 | -55,250,425 |
