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 61,466,503, 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 | 61,466,503 | |
| -1 | -61,466,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,466,503.
Example:
1 x 61,466,503 = 61,466,503
and
-1 x -61,466,503 = 61,466,503
Notice both answers equal 61,466,503
With that explanation out of the way, let's continue. Next, we take the number 61,466,503 and divide it by 2:
61,466,503 ÷ 2 = 30,733,251.5
If the quotient is a whole number, then 2 and 30,733,251.5 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 | 61,466,503 | |
| -1 | -61,466,503 |
Now, we try dividing 61,466,503 by 3:
61,466,503 ÷ 3 = 20,488,834.3333
If the quotient is a whole number, then 3 and 20,488,834.3333 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 | 61,466,503 | |
| -1 | -61,466,503 |
Let's try dividing by 4:
61,466,503 ÷ 4 = 15,366,625.75
If the quotient is a whole number, then 4 and 15,366,625.75 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 | 61,466,503 | |
| -1 | 61,466,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 79 | 287 | 553 | 2,711 | 3,239 | 18,977 | 22,673 | 111,151 | 214,169 | 778,057 | 1,499,183 | 8,780,929 | 61,466,503 |
| -1 | -7 | -41 | -79 | -287 | -553 | -2,711 | -3,239 | -18,977 | -22,673 | -111,151 | -214,169 | -778,057 | -1,499,183 | -8,780,929 | -61,466,503 |
