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 75,035,741, 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 | 75,035,741 | |
| -1 | -75,035,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 75,035,741.
Example:
1 x 75,035,741 = 75,035,741
and
-1 x -75,035,741 = 75,035,741
Notice both answers equal 75,035,741
With that explanation out of the way, let's continue. Next, we take the number 75,035,741 and divide it by 2:
75,035,741 ÷ 2 = 37,517,870.5
If the quotient is a whole number, then 2 and 37,517,870.5 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 | 75,035,741 | |
| -1 | -75,035,741 |
Now, we try dividing 75,035,741 by 3:
75,035,741 ÷ 3 = 25,011,913.6667
If the quotient is a whole number, then 3 and 25,011,913.6667 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 | 75,035,741 | |
| -1 | -75,035,741 |
Let's try dividing by 4:
75,035,741 ÷ 4 = 18,758,935.25
If the quotient is a whole number, then 4 and 18,758,935.25 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 | 75,035,741 | |
| -1 | 75,035,741 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 263 | 407 | 701 | 2,893 | 7,711 | 9,731 | 25,937 | 107,041 | 184,363 | 285,307 | 2,027,993 | 6,821,431 | 75,035,741 |
| -1 | -11 | -37 | -263 | -407 | -701 | -2,893 | -7,711 | -9,731 | -25,937 | -107,041 | -184,363 | -285,307 | -2,027,993 | -6,821,431 | -75,035,741 |
