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 203,473,025, 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 | 203,473,025 | |
| -1 | -203,473,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,473,025.
Example:
1 x 203,473,025 = 203,473,025
and
-1 x -203,473,025 = 203,473,025
Notice both answers equal 203,473,025
With that explanation out of the way, let's continue. Next, we take the number 203,473,025 and divide it by 2:
203,473,025 ÷ 2 = 101,736,512.5
If the quotient is a whole number, then 2 and 101,736,512.5 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 | 203,473,025 | |
| -1 | -203,473,025 |
Now, we try dividing 203,473,025 by 3:
203,473,025 ÷ 3 = 67,824,341.6667
If the quotient is a whole number, then 3 and 67,824,341.6667 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 | 203,473,025 | |
| -1 | -203,473,025 |
Let's try dividing by 4:
203,473,025 ÷ 4 = 50,868,256.25
If the quotient is a whole number, then 4 and 50,868,256.25 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 | 203,473,025 | |
| -1 | 203,473,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 109 | 175 | 545 | 763 | 2,725 | 3,815 | 10,667 | 19,075 | 53,335 | 74,669 | 266,675 | 373,345 | 1,162,703 | 1,866,725 | 5,813,515 | 8,138,921 | 29,067,575 | 40,694,605 | 203,473,025 |
| -1 | -5 | -7 | -25 | -35 | -109 | -175 | -545 | -763 | -2,725 | -3,815 | -10,667 | -19,075 | -53,335 | -74,669 | -266,675 | -373,345 | -1,162,703 | -1,866,725 | -5,813,515 | -8,138,921 | -29,067,575 | -40,694,605 | -203,473,025 |
