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 535,187,245, 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 | 535,187,245 | |
| -1 | -535,187,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 535,187,245.
Example:
1 x 535,187,245 = 535,187,245
and
-1 x -535,187,245 = 535,187,245
Notice both answers equal 535,187,245
With that explanation out of the way, let's continue. Next, we take the number 535,187,245 and divide it by 2:
535,187,245 ÷ 2 = 267,593,622.5
If the quotient is a whole number, then 2 and 267,593,622.5 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 | 535,187,245 | |
| -1 | -535,187,245 |
Now, we try dividing 535,187,245 by 3:
535,187,245 ÷ 3 = 178,395,748.3333
If the quotient is a whole number, then 3 and 178,395,748.3333 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 | 535,187,245 | |
| -1 | -535,187,245 |
Let's try dividing by 4:
535,187,245 ÷ 4 = 133,796,811.25
If the quotient is a whole number, then 4 and 133,796,811.25 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 | 535,187,245 | |
| -1 | 535,187,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 1,549 | 1,607 | 7,745 | 8,035 | 66,607 | 69,101 | 333,035 | 345,505 | 2,489,243 | 12,446,215 | 107,037,449 | 535,187,245 |
| -1 | -5 | -43 | -215 | -1,549 | -1,607 | -7,745 | -8,035 | -66,607 | -69,101 | -333,035 | -345,505 | -2,489,243 | -12,446,215 | -107,037,449 | -535,187,245 |
