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 62,640,895, 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 | 62,640,895 | |
| -1 | -62,640,895 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,640,895.
Example:
1 x 62,640,895 = 62,640,895
and
-1 x -62,640,895 = 62,640,895
Notice both answers equal 62,640,895
With that explanation out of the way, let's continue. Next, we take the number 62,640,895 and divide it by 2:
62,640,895 ÷ 2 = 31,320,447.5
If the quotient is a whole number, then 2 and 31,320,447.5 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 | 62,640,895 | |
| -1 | -62,640,895 |
Now, we try dividing 62,640,895 by 3:
62,640,895 ÷ 3 = 20,880,298.3333
If the quotient is a whole number, then 3 and 20,880,298.3333 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 | 62,640,895 | |
| -1 | -62,640,895 |
Let's try dividing by 4:
62,640,895 ÷ 4 = 15,660,223.75
If the quotient is a whole number, then 4 and 15,660,223.75 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 | 62,640,895 | |
| -1 | 62,640,895 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 47 | 215 | 235 | 2,021 | 6,199 | 10,105 | 30,995 | 266,557 | 291,353 | 1,332,785 | 1,456,765 | 12,528,179 | 62,640,895 |
| -1 | -5 | -43 | -47 | -215 | -235 | -2,021 | -6,199 | -10,105 | -30,995 | -266,557 | -291,353 | -1,332,785 | -1,456,765 | -12,528,179 | -62,640,895 |
