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 100,620,275, 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 | 100,620,275 | |
| -1 | -100,620,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,620,275.
Example:
1 x 100,620,275 = 100,620,275
and
-1 x -100,620,275 = 100,620,275
Notice both answers equal 100,620,275
With that explanation out of the way, let's continue. Next, we take the number 100,620,275 and divide it by 2:
100,620,275 ÷ 2 = 50,310,137.5
If the quotient is a whole number, then 2 and 50,310,137.5 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 | 100,620,275 | |
| -1 | -100,620,275 |
Now, we try dividing 100,620,275 by 3:
100,620,275 ÷ 3 = 33,540,091.6667
If the quotient is a whole number, then 3 and 33,540,091.6667 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 | 100,620,275 | |
| -1 | -100,620,275 |
Let's try dividing by 4:
100,620,275 ÷ 4 = 25,155,068.75
If the quotient is a whole number, then 4 and 25,155,068.75 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 | 100,620,275 | |
| -1 | 100,620,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 82,139 | 410,695 | 574,973 | 2,053,475 | 2,874,865 | 4,024,811 | 14,374,325 | 20,124,055 | 100,620,275 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -82,139 | -410,695 | -574,973 | -2,053,475 | -2,874,865 | -4,024,811 | -14,374,325 | -20,124,055 | -100,620,275 |
