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 253,224,335, 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 | 253,224,335 | |
| -1 | -253,224,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 253,224,335.
Example:
1 x 253,224,335 = 253,224,335
and
-1 x -253,224,335 = 253,224,335
Notice both answers equal 253,224,335
With that explanation out of the way, let's continue. Next, we take the number 253,224,335 and divide it by 2:
253,224,335 ÷ 2 = 126,612,167.5
If the quotient is a whole number, then 2 and 126,612,167.5 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 | 253,224,335 | |
| -1 | -253,224,335 |
Now, we try dividing 253,224,335 by 3:
253,224,335 ÷ 3 = 84,408,111.6667
If the quotient is a whole number, then 3 and 84,408,111.6667 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 | 253,224,335 | |
| -1 | -253,224,335 |
Let's try dividing by 4:
253,224,335 ÷ 4 = 63,306,083.75
If the quotient is a whole number, then 4 and 63,306,083.75 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 | 253,224,335 | |
| -1 | 253,224,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 556,537 | 2,782,685 | 3,895,759 | 7,234,981 | 19,478,795 | 36,174,905 | 50,644,867 | 253,224,335 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -556,537 | -2,782,685 | -3,895,759 | -7,234,981 | -19,478,795 | -36,174,905 | -50,644,867 | -253,224,335 |
