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 243,424,465, 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 | 243,424,465 | |
| -1 | -243,424,465 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,424,465.
Example:
1 x 243,424,465 = 243,424,465
and
-1 x -243,424,465 = 243,424,465
Notice both answers equal 243,424,465
With that explanation out of the way, let's continue. Next, we take the number 243,424,465 and divide it by 2:
243,424,465 ÷ 2 = 121,712,232.5
If the quotient is a whole number, then 2 and 121,712,232.5 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 | 243,424,465 | |
| -1 | -243,424,465 |
Now, we try dividing 243,424,465 by 3:
243,424,465 ÷ 3 = 81,141,488.3333
If the quotient is a whole number, then 3 and 81,141,488.3333 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 | 243,424,465 | |
| -1 | -243,424,465 |
Let's try dividing by 4:
243,424,465 ÷ 4 = 60,856,116.25
If the quotient is a whole number, then 4 and 60,856,116.25 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 | 243,424,465 | |
| -1 | 243,424,465 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 107 | 305 | 535 | 6,527 | 7,459 | 32,635 | 37,295 | 454,999 | 798,113 | 2,274,995 | 3,990,565 | 48,684,893 | 243,424,465 |
| -1 | -5 | -61 | -107 | -305 | -535 | -6,527 | -7,459 | -32,635 | -37,295 | -454,999 | -798,113 | -2,274,995 | -3,990,565 | -48,684,893 | -243,424,465 |
