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 75,743,675, 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 | 75,743,675 | |
| -1 | -75,743,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,743,675.
Example:
1 x 75,743,675 = 75,743,675
and
-1 x -75,743,675 = 75,743,675
Notice both answers equal 75,743,675
With that explanation out of the way, let's continue. Next, we take the number 75,743,675 and divide it by 2:
75,743,675 ÷ 2 = 37,871,837.5
If the quotient is a whole number, then 2 and 37,871,837.5 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 | 75,743,675 | |
| -1 | -75,743,675 |
Now, we try dividing 75,743,675 by 3:
75,743,675 ÷ 3 = 25,247,891.6667
If the quotient is a whole number, then 3 and 25,247,891.6667 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 | 75,743,675 | |
| -1 | -75,743,675 |
Let's try dividing by 4:
75,743,675 ÷ 4 = 18,935,918.75
If the quotient is a whole number, then 4 and 18,935,918.75 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 | 75,743,675 | |
| -1 | 75,743,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 269 | 1,345 | 1,609 | 1,883 | 6,725 | 8,045 | 9,415 | 11,263 | 40,225 | 47,075 | 56,315 | 281,575 | 432,821 | 2,164,105 | 3,029,747 | 10,820,525 | 15,148,735 | 75,743,675 |
| -1 | -5 | -7 | -25 | -35 | -175 | -269 | -1,345 | -1,609 | -1,883 | -6,725 | -8,045 | -9,415 | -11,263 | -40,225 | -47,075 | -56,315 | -281,575 | -432,821 | -2,164,105 | -3,029,747 | -10,820,525 | -15,148,735 | -75,743,675 |
