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 653,146,451, 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 | 653,146,451 | |
| -1 | -653,146,451 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 653,146,451.
Example:
1 x 653,146,451 = 653,146,451
and
-1 x -653,146,451 = 653,146,451
Notice both answers equal 653,146,451
With that explanation out of the way, let's continue. Next, we take the number 653,146,451 and divide it by 2:
653,146,451 ÷ 2 = 326,573,225.5
If the quotient is a whole number, then 2 and 326,573,225.5 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 | 653,146,451 | |
| -1 | -653,146,451 |
Now, we try dividing 653,146,451 by 3:
653,146,451 ÷ 3 = 217,715,483.6667
If the quotient is a whole number, then 3 and 217,715,483.6667 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 | 653,146,451 | |
| -1 | -653,146,451 |
Let's try dividing by 4:
653,146,451 ÷ 4 = 163,286,612.75
If the quotient is a whole number, then 4 and 163,286,612.75 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 | 653,146,451 | |
| -1 | 653,146,451 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 431 | 893 | 1,697 | 8,189 | 20,257 | 32,243 | 79,759 | 384,883 | 731,407 | 1,515,421 | 13,896,733 | 34,376,129 | 653,146,451 |
| -1 | -19 | -47 | -431 | -893 | -1,697 | -8,189 | -20,257 | -32,243 | -79,759 | -384,883 | -731,407 | -1,515,421 | -13,896,733 | -34,376,129 | -653,146,451 |
