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 100,853,425, 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 | 100,853,425 | |
| -1 | -100,853,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,853,425.
Example:
1 x 100,853,425 = 100,853,425
and
-1 x -100,853,425 = 100,853,425
Notice both answers equal 100,853,425
With that explanation out of the way, let's continue. Next, we take the number 100,853,425 and divide it by 2:
100,853,425 ÷ 2 = 50,426,712.5
If the quotient is a whole number, then 2 and 50,426,712.5 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 | 100,853,425 | |
| -1 | -100,853,425 |
Now, we try dividing 100,853,425 by 3:
100,853,425 ÷ 3 = 33,617,808.3333
If the quotient is a whole number, then 3 and 33,617,808.3333 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 | 100,853,425 | |
| -1 | -100,853,425 |
Let's try dividing by 4:
100,853,425 ÷ 4 = 25,213,356.25
If the quotient is a whole number, then 4 and 25,213,356.25 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 | 100,853,425 | |
| -1 | 100,853,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 67 | 95 | 335 | 475 | 1,273 | 1,675 | 3,169 | 6,365 | 15,845 | 31,825 | 60,211 | 79,225 | 212,323 | 301,055 | 1,061,615 | 1,505,275 | 4,034,137 | 5,308,075 | 20,170,685 | 100,853,425 |
| -1 | -5 | -19 | -25 | -67 | -95 | -335 | -475 | -1,273 | -1,675 | -3,169 | -6,365 | -15,845 | -31,825 | -60,211 | -79,225 | -212,323 | -301,055 | -1,061,615 | -1,505,275 | -4,034,137 | -5,308,075 | -20,170,685 | -100,853,425 |
