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 51,341,275, 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 | 51,341,275 | |
| -1 | -51,341,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,341,275.
Example:
1 x 51,341,275 = 51,341,275
and
-1 x -51,341,275 = 51,341,275
Notice both answers equal 51,341,275
With that explanation out of the way, let's continue. Next, we take the number 51,341,275 and divide it by 2:
51,341,275 ÷ 2 = 25,670,637.5
If the quotient is a whole number, then 2 and 25,670,637.5 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 | 51,341,275 | |
| -1 | -51,341,275 |
Now, we try dividing 51,341,275 by 3:
51,341,275 ÷ 3 = 17,113,758.3333
If the quotient is a whole number, then 3 and 17,113,758.3333 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 | 51,341,275 | |
| -1 | -51,341,275 |
Let's try dividing by 4:
51,341,275 ÷ 4 = 12,835,318.75
If the quotient is a whole number, then 4 and 12,835,318.75 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 | 51,341,275 | |
| -1 | 51,341,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 107 | 425 | 535 | 1,129 | 1,819 | 2,675 | 5,645 | 9,095 | 19,193 | 28,225 | 45,475 | 95,965 | 120,803 | 479,825 | 604,015 | 2,053,651 | 3,020,075 | 10,268,255 | 51,341,275 |
| -1 | -5 | -17 | -25 | -85 | -107 | -425 | -535 | -1,129 | -1,819 | -2,675 | -5,645 | -9,095 | -19,193 | -28,225 | -45,475 | -95,965 | -120,803 | -479,825 | -604,015 | -2,053,651 | -3,020,075 | -10,268,255 | -51,341,275 |
