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 45,731,075, 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 | 45,731,075 | |
| -1 | -45,731,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 45,731,075.
Example:
1 x 45,731,075 = 45,731,075
and
-1 x -45,731,075 = 45,731,075
Notice both answers equal 45,731,075
With that explanation out of the way, let's continue. Next, we take the number 45,731,075 and divide it by 2:
45,731,075 ÷ 2 = 22,865,537.5
If the quotient is a whole number, then 2 and 22,865,537.5 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 | 45,731,075 | |
| -1 | -45,731,075 |
Now, we try dividing 45,731,075 by 3:
45,731,075 ÷ 3 = 15,243,691.6667
If the quotient is a whole number, then 3 and 15,243,691.6667 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 | 45,731,075 | |
| -1 | -45,731,075 |
Let's try dividing by 4:
45,731,075 ÷ 4 = 11,432,768.75
If the quotient is a whole number, then 4 and 11,432,768.75 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 | 45,731,075 | |
| -1 | 45,731,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 37 | 65 | 185 | 325 | 481 | 925 | 2,405 | 3,803 | 12,025 | 19,015 | 49,439 | 95,075 | 140,711 | 247,195 | 703,555 | 1,235,975 | 1,829,243 | 3,517,775 | 9,146,215 | 45,731,075 |
| -1 | -5 | -13 | -25 | -37 | -65 | -185 | -325 | -481 | -925 | -2,405 | -3,803 | -12,025 | -19,015 | -49,439 | -95,075 | -140,711 | -247,195 | -703,555 | -1,235,975 | -1,829,243 | -3,517,775 | -9,146,215 | -45,731,075 |
