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 53,366,677, 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 | 53,366,677 | |
| -1 | -53,366,677 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,366,677.
Example:
1 x 53,366,677 = 53,366,677
and
-1 x -53,366,677 = 53,366,677
Notice both answers equal 53,366,677
With that explanation out of the way, let's continue. Next, we take the number 53,366,677 and divide it by 2:
53,366,677 ÷ 2 = 26,683,338.5
If the quotient is a whole number, then 2 and 26,683,338.5 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 | 53,366,677 | |
| -1 | -53,366,677 |
Now, we try dividing 53,366,677 by 3:
53,366,677 ÷ 3 = 17,788,892.3333
If the quotient is a whole number, then 3 and 17,788,892.3333 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 | 53,366,677 | |
| -1 | -53,366,677 |
Let's try dividing by 4:
53,366,677 ÷ 4 = 13,341,669.25
If the quotient is a whole number, then 4 and 13,341,669.25 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 | 53,366,677 | |
| -1 | 53,366,677 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 281 | 1,967 | 2,087 | 3,653 | 14,609 | 25,571 | 27,131 | 189,917 | 586,447 | 4,105,129 | 7,623,811 | 53,366,677 |
| -1 | -7 | -13 | -91 | -281 | -1,967 | -2,087 | -3,653 | -14,609 | -25,571 | -27,131 | -189,917 | -586,447 | -4,105,129 | -7,623,811 | -53,366,677 |
