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 247,746,653, 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 | 247,746,653 | |
| -1 | -247,746,653 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 247,746,653.
Example:
1 x 247,746,653 = 247,746,653
and
-1 x -247,746,653 = 247,746,653
Notice both answers equal 247,746,653
With that explanation out of the way, let's continue. Next, we take the number 247,746,653 and divide it by 2:
247,746,653 ÷ 2 = 123,873,326.5
If the quotient is a whole number, then 2 and 123,873,326.5 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 | 247,746,653 | |
| -1 | -247,746,653 |
Now, we try dividing 247,746,653 by 3:
247,746,653 ÷ 3 = 82,582,217.6667
If the quotient is a whole number, then 3 and 82,582,217.6667 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 | 247,746,653 | |
| -1 | -247,746,653 |
Let's try dividing by 4:
247,746,653 ÷ 4 = 61,936,663.25
If the quotient is a whole number, then 4 and 61,936,663.25 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 | 247,746,653 | |
| -1 | 247,746,653 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 121 | 367 | 797 | 847 | 2,569 | 4,037 | 5,579 | 8,767 | 28,259 | 44,407 | 61,369 | 96,437 | 292,499 | 310,849 | 675,059 | 2,047,493 | 3,217,489 | 22,522,423 | 35,392,379 | 247,746,653 |
| -1 | -7 | -11 | -77 | -121 | -367 | -797 | -847 | -2,569 | -4,037 | -5,579 | -8,767 | -28,259 | -44,407 | -61,369 | -96,437 | -292,499 | -310,849 | -675,059 | -2,047,493 | -3,217,489 | -22,522,423 | -35,392,379 | -247,746,653 |
