Find the Prime Factorization 55

Problem

55

Solution

1. Identify the smallest prime number that divides the given number. Since 55 is odd, it is not divisible by 2. The sum of the digits 5 + 5 = 10$ is not divisible by 3, so 55 is not divisible by 3.

2. Divide by the next prime number, which is 5. Since 55 ends in 5, it is divisible by 5.

3. Calculate the quotient of the division.

55÷5=11

4. Check if the quotient is a prime number. Since 11 is a prime number, the factorization process is complete.

5. Express the number as a product of its prime factors.

55=5×11

Final Answer

55=5×11
