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 62,521,277, 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 | 62,521,277 | |
| -1 | -62,521,277 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 62,521,277.
Example:
1 x 62,521,277 = 62,521,277
and
-1 x -62,521,277 = 62,521,277
Notice both answers equal 62,521,277
With that explanation out of the way, let's continue. Next, we take the number 62,521,277 and divide it by 2:
62,521,277 ÷ 2 = 31,260,638.5
If the quotient is a whole number, then 2 and 31,260,638.5 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 | 62,521,277 | |
| -1 | -62,521,277 |
Now, we try dividing 62,521,277 by 3:
62,521,277 ÷ 3 = 20,840,425.6667
If the quotient is a whole number, then 3 and 20,840,425.6667 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 | 62,521,277 | |
| -1 | -62,521,277 |
Let's try dividing by 4:
62,521,277 ÷ 4 = 15,630,319.25
If the quotient is a whole number, then 4 and 15,630,319.25 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 | 62,521,277 | |
| -1 | 62,521,277 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 107 | 749 | 1,391 | 6,421 | 9,737 | 44,947 | 83,473 | 584,311 | 687,047 | 4,809,329 | 8,931,611 | 62,521,277 |
| -1 | -7 | -13 | -91 | -107 | -749 | -1,391 | -6,421 | -9,737 | -44,947 | -83,473 | -584,311 | -687,047 | -4,809,329 | -8,931,611 | -62,521,277 |
