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 38,827,075, 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 | 38,827,075 | |
| -1 | -38,827,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 38,827,075.
Example:
1 x 38,827,075 = 38,827,075
and
-1 x -38,827,075 = 38,827,075
Notice both answers equal 38,827,075
With that explanation out of the way, let's continue. Next, we take the number 38,827,075 and divide it by 2:
38,827,075 ÷ 2 = 19,413,537.5
If the quotient is a whole number, then 2 and 19,413,537.5 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 | 38,827,075 | |
| -1 | -38,827,075 |
Now, we try dividing 38,827,075 by 3:
38,827,075 ÷ 3 = 12,942,358.3333
If the quotient is a whole number, then 3 and 12,942,358.3333 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 | 38,827,075 | |
| -1 | -38,827,075 |
Let's try dividing by 4:
38,827,075 ÷ 4 = 9,706,768.75
If the quotient is a whole number, then 4 and 9,706,768.75 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 | 38,827,075 | |
| -1 | 38,827,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 127 | 175 | 635 | 889 | 1,747 | 3,175 | 4,445 | 8,735 | 12,229 | 22,225 | 43,675 | 61,145 | 221,869 | 305,725 | 1,109,345 | 1,553,083 | 5,546,725 | 7,765,415 | 38,827,075 |
| -1 | -5 | -7 | -25 | -35 | -127 | -175 | -635 | -889 | -1,747 | -3,175 | -4,445 | -8,735 | -12,229 | -22,225 | -43,675 | -61,145 | -221,869 | -305,725 | -1,109,345 | -1,553,083 | -5,546,725 | -7,765,415 | -38,827,075 |
