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 61,775,371, 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 | 61,775,371 | |
| -1 | -61,775,371 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,775,371.
Example:
1 x 61,775,371 = 61,775,371
and
-1 x -61,775,371 = 61,775,371
Notice both answers equal 61,775,371
With that explanation out of the way, let's continue. Next, we take the number 61,775,371 and divide it by 2:
61,775,371 ÷ 2 = 30,887,685.5
If the quotient is a whole number, then 2 and 30,887,685.5 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 | 61,775,371 | |
| -1 | -61,775,371 |
Now, we try dividing 61,775,371 by 3:
61,775,371 ÷ 3 = 20,591,790.3333
If the quotient is a whole number, then 3 and 20,591,790.3333 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 | 61,775,371 | |
| -1 | -61,775,371 |
Let's try dividing by 4:
61,775,371 ÷ 4 = 15,443,842.75
If the quotient is a whole number, then 4 and 15,443,842.75 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 | 61,775,371 | |
| -1 | 61,775,371 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 199 | 427 | 727 | 1,393 | 5,089 | 12,139 | 44,347 | 84,973 | 144,673 | 310,429 | 1,012,711 | 8,825,053 | 61,775,371 |
| -1 | -7 | -61 | -199 | -427 | -727 | -1,393 | -5,089 | -12,139 | -44,347 | -84,973 | -144,673 | -310,429 | -1,012,711 | -8,825,053 | -61,775,371 |
