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 53,076,155, 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 | 53,076,155 | |
| -1 | -53,076,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 53,076,155.
Example:
1 x 53,076,155 = 53,076,155
and
-1 x -53,076,155 = 53,076,155
Notice both answers equal 53,076,155
With that explanation out of the way, let's continue. Next, we take the number 53,076,155 and divide it by 2:
53,076,155 ÷ 2 = 26,538,077.5
If the quotient is a whole number, then 2 and 26,538,077.5 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 | 53,076,155 | |
| -1 | -53,076,155 |
Now, we try dividing 53,076,155 by 3:
53,076,155 ÷ 3 = 17,692,051.6667
If the quotient is a whole number, then 3 and 17,692,051.6667 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 | 53,076,155 | |
| -1 | -53,076,155 |
Let's try dividing by 4:
53,076,155 ÷ 4 = 13,269,038.75
If the quotient is a whole number, then 4 and 13,269,038.75 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 | 53,076,155 | |
| -1 | 53,076,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 619 | 1,559 | 3,095 | 6,809 | 7,795 | 17,149 | 34,045 | 85,745 | 965,021 | 4,825,105 | 10,615,231 | 53,076,155 |
| -1 | -5 | -11 | -55 | -619 | -1,559 | -3,095 | -6,809 | -7,795 | -17,149 | -34,045 | -85,745 | -965,021 | -4,825,105 | -10,615,231 | -53,076,155 |
