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 371,114,725, 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 | 371,114,725 | |
| -1 | -371,114,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 371,114,725.
Example:
1 x 371,114,725 = 371,114,725
and
-1 x -371,114,725 = 371,114,725
Notice both answers equal 371,114,725
With that explanation out of the way, let's continue. Next, we take the number 371,114,725 and divide it by 2:
371,114,725 ÷ 2 = 185,557,362.5
If the quotient is a whole number, then 2 and 185,557,362.5 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 | 371,114,725 | |
| -1 | -371,114,725 |
Now, we try dividing 371,114,725 by 3:
371,114,725 ÷ 3 = 123,704,908.3333
If the quotient is a whole number, then 3 and 123,704,908.3333 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 | 371,114,725 | |
| -1 | -371,114,725 |
Let's try dividing by 4:
371,114,725 ÷ 4 = 92,778,681.25
If the quotient is a whole number, then 4 and 92,778,681.25 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 | 371,114,725 | |
| -1 | 371,114,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 97 | 215 | 485 | 1,075 | 2,425 | 3,559 | 4,171 | 17,795 | 20,855 | 88,975 | 104,275 | 153,037 | 345,223 | 765,185 | 1,726,115 | 3,825,925 | 8,630,575 | 14,844,589 | 74,222,945 | 371,114,725 |
| -1 | -5 | -25 | -43 | -97 | -215 | -485 | -1,075 | -2,425 | -3,559 | -4,171 | -17,795 | -20,855 | -88,975 | -104,275 | -153,037 | -345,223 | -765,185 | -1,726,115 | -3,825,925 | -8,630,575 | -14,844,589 | -74,222,945 | -371,114,725 |
