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 61,551,203, 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 | 61,551,203 | |
| -1 | -61,551,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 61,551,203.
Example:
1 x 61,551,203 = 61,551,203
and
-1 x -61,551,203 = 61,551,203
Notice both answers equal 61,551,203
With that explanation out of the way, let's continue. Next, we take the number 61,551,203 and divide it by 2:
61,551,203 ÷ 2 = 30,775,601.5
If the quotient is a whole number, then 2 and 30,775,601.5 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 | 61,551,203 | |
| -1 | -61,551,203 |
Now, we try dividing 61,551,203 by 3:
61,551,203 ÷ 3 = 20,517,067.6667
If the quotient is a whole number, then 3 and 20,517,067.6667 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 | 61,551,203 | |
| -1 | -61,551,203 |
Let's try dividing by 4:
61,551,203 ÷ 4 = 15,387,800.75
If the quotient is a whole number, then 4 and 15,387,800.75 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 | 61,551,203 | |
| -1 | 61,551,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 49 | 119 | 133 | 323 | 833 | 931 | 2,261 | 3,889 | 15,827 | 27,223 | 66,113 | 73,891 | 190,561 | 462,791 | 517,237 | 1,256,147 | 3,239,537 | 3,620,659 | 8,793,029 | 61,551,203 |
| -1 | -7 | -17 | -19 | -49 | -119 | -133 | -323 | -833 | -931 | -2,261 | -3,889 | -15,827 | -27,223 | -66,113 | -73,891 | -190,561 | -462,791 | -517,237 | -1,256,147 | -3,239,537 | -3,620,659 | -8,793,029 | -61,551,203 |
