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 38,740,075, 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 | 38,740,075 | |
| -1 | -38,740,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,740,075.
Example:
1 x 38,740,075 = 38,740,075
and
-1 x -38,740,075 = 38,740,075
Notice both answers equal 38,740,075
With that explanation out of the way, let's continue. Next, we take the number 38,740,075 and divide it by 2:
38,740,075 ÷ 2 = 19,370,037.5
If the quotient is a whole number, then 2 and 19,370,037.5 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 | 38,740,075 | |
| -1 | -38,740,075 |
Now, we try dividing 38,740,075 by 3:
38,740,075 ÷ 3 = 12,913,358.3333
If the quotient is a whole number, then 3 and 12,913,358.3333 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 | 38,740,075 | |
| -1 | -38,740,075 |
Let's try dividing by 4:
38,740,075 ÷ 4 = 9,685,018.75
If the quotient is a whole number, then 4 and 9,685,018.75 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 | 38,740,075 | |
| -1 | 38,740,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 179 | 275 | 787 | 895 | 1,969 | 3,935 | 4,475 | 8,657 | 9,845 | 19,675 | 43,285 | 49,225 | 140,873 | 216,425 | 704,365 | 1,549,603 | 3,521,825 | 7,748,015 | 38,740,075 |
| -1 | -5 | -11 | -25 | -55 | -179 | -275 | -787 | -895 | -1,969 | -3,935 | -4,475 | -8,657 | -9,845 | -19,675 | -43,285 | -49,225 | -140,873 | -216,425 | -704,365 | -1,549,603 | -3,521,825 | -7,748,015 | -38,740,075 |
