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 202,053,565, 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 | 202,053,565 | |
| -1 | -202,053,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 202,053,565.
Example:
1 x 202,053,565 = 202,053,565
and
-1 x -202,053,565 = 202,053,565
Notice both answers equal 202,053,565
With that explanation out of the way, let's continue. Next, we take the number 202,053,565 and divide it by 2:
202,053,565 ÷ 2 = 101,026,782.5
If the quotient is a whole number, then 2 and 101,026,782.5 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 | 202,053,565 | |
| -1 | -202,053,565 |
Now, we try dividing 202,053,565 by 3:
202,053,565 ÷ 3 = 67,351,188.3333
If the quotient is a whole number, then 3 and 67,351,188.3333 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 | 202,053,565 | |
| -1 | -202,053,565 |
Let's try dividing by 4:
202,053,565 ÷ 4 = 50,513,391.25
If the quotient is a whole number, then 4 and 50,513,391.25 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 | 202,053,565 | |
| -1 | 202,053,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 383 | 1,915 | 2,681 | 13,405 | 15,073 | 75,365 | 105,511 | 527,555 | 5,772,959 | 28,864,795 | 40,410,713 | 202,053,565 |
| -1 | -5 | -7 | -35 | -383 | -1,915 | -2,681 | -13,405 | -15,073 | -75,365 | -105,511 | -527,555 | -5,772,959 | -28,864,795 | -40,410,713 | -202,053,565 |
