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 735,072,541, 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 | 735,072,541 | |
| -1 | -735,072,541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 735,072,541.
Example:
1 x 735,072,541 = 735,072,541
and
-1 x -735,072,541 = 735,072,541
Notice both answers equal 735,072,541
With that explanation out of the way, let's continue. Next, we take the number 735,072,541 and divide it by 2:
735,072,541 ÷ 2 = 367,536,270.5
If the quotient is a whole number, then 2 and 367,536,270.5 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 | 735,072,541 | |
| -1 | -735,072,541 |
Now, we try dividing 735,072,541 by 3:
735,072,541 ÷ 3 = 245,024,180.3333
If the quotient is a whole number, then 3 and 245,024,180.3333 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 | 735,072,541 | |
| -1 | -735,072,541 |
Let's try dividing by 4:
735,072,541 ÷ 4 = 183,768,135.25
If the quotient is a whole number, then 4 and 183,768,135.25 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 | 735,072,541 | |
| -1 | 735,072,541 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 137 | 203 | 959 | 3,973 | 26,431 | 27,811 | 185,017 | 766,499 | 3,621,047 | 5,365,493 | 25,347,329 | 105,010,363 | 735,072,541 |
| -1 | -7 | -29 | -137 | -203 | -959 | -3,973 | -26,431 | -27,811 | -185,017 | -766,499 | -3,621,047 | -5,365,493 | -25,347,329 | -105,010,363 | -735,072,541 |
