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 64,610,251, 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 | 64,610,251 | |
| -1 | -64,610,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 64,610,251.
Example:
1 x 64,610,251 = 64,610,251
and
-1 x -64,610,251 = 64,610,251
Notice both answers equal 64,610,251
With that explanation out of the way, let's continue. Next, we take the number 64,610,251 and divide it by 2:
64,610,251 ÷ 2 = 32,305,125.5
If the quotient is a whole number, then 2 and 32,305,125.5 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 | 64,610,251 | |
| -1 | -64,610,251 |
Now, we try dividing 64,610,251 by 3:
64,610,251 ÷ 3 = 21,536,750.3333
If the quotient is a whole number, then 3 and 21,536,750.3333 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 | 64,610,251 | |
| -1 | -64,610,251 |
Let's try dividing by 4:
64,610,251 ÷ 4 = 16,152,562.75
If the quotient is a whole number, then 4 and 16,152,562.75 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 | 64,610,251 | |
| -1 | 64,610,251 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 59 | 629 | 1,003 | 1,741 | 2,183 | 29,597 | 37,111 | 64,417 | 102,719 | 1,095,089 | 1,746,223 | 3,800,603 | 64,610,251 |
| -1 | -17 | -37 | -59 | -629 | -1,003 | -1,741 | -2,183 | -29,597 | -37,111 | -64,417 | -102,719 | -1,095,089 | -1,746,223 | -3,800,603 | -64,610,251 |
