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 51,562,315, 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 | 51,562,315 | |
| -1 | -51,562,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,562,315.
Example:
1 x 51,562,315 = 51,562,315
and
-1 x -51,562,315 = 51,562,315
Notice both answers equal 51,562,315
With that explanation out of the way, let's continue. Next, we take the number 51,562,315 and divide it by 2:
51,562,315 ÷ 2 = 25,781,157.5
If the quotient is a whole number, then 2 and 25,781,157.5 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 | 51,562,315 | |
| -1 | -51,562,315 |
Now, we try dividing 51,562,315 by 3:
51,562,315 ÷ 3 = 17,187,438.3333
If the quotient is a whole number, then 3 and 17,187,438.3333 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 | 51,562,315 | |
| -1 | -51,562,315 |
Let's try dividing by 4:
51,562,315 ÷ 4 = 12,890,578.75
If the quotient is a whole number, then 4 and 12,890,578.75 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 | 51,562,315 | |
| -1 | 51,562,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 3,605 | 14,303 | 71,515 | 100,121 | 500,605 | 1,473,209 | 7,366,045 | 10,312,463 | 51,562,315 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -3,605 | -14,303 | -71,515 | -100,121 | -500,605 | -1,473,209 | -7,366,045 | -10,312,463 | -51,562,315 |
