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 37,819,075, 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 | 37,819,075 | |
| -1 | -37,819,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 37,819,075.
Example:
1 x 37,819,075 = 37,819,075
and
-1 x -37,819,075 = 37,819,075
Notice both answers equal 37,819,075
With that explanation out of the way, let's continue. Next, we take the number 37,819,075 and divide it by 2:
37,819,075 ÷ 2 = 18,909,537.5
If the quotient is a whole number, then 2 and 18,909,537.5 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 | 37,819,075 | |
| -1 | -37,819,075 |
Now, we try dividing 37,819,075 by 3:
37,819,075 ÷ 3 = 12,606,358.3333
If the quotient is a whole number, then 3 and 12,606,358.3333 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 | 37,819,075 | |
| -1 | -37,819,075 |
Let's try dividing by 4:
37,819,075 ÷ 4 = 9,454,768.75
If the quotient is a whole number, then 4 and 9,454,768.75 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 | 37,819,075 | |
| -1 | 37,819,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 197 | 985 | 1,097 | 1,379 | 4,925 | 5,485 | 6,895 | 7,679 | 27,425 | 34,475 | 38,395 | 191,975 | 216,109 | 1,080,545 | 1,512,763 | 5,402,725 | 7,563,815 | 37,819,075 |
| -1 | -5 | -7 | -25 | -35 | -175 | -197 | -985 | -1,097 | -1,379 | -4,925 | -5,485 | -6,895 | -7,679 | -27,425 | -34,475 | -38,395 | -191,975 | -216,109 | -1,080,545 | -1,512,763 | -5,402,725 | -7,563,815 | -37,819,075 |
