Question

hcf of 518 and 888 by prime factorization method ​

Answer 1

Prime Factorization of a number: finding the prime numbers that multiply together to make that number.

518 = 2 × 7 × 37;

518 is not a prime, is a composite number;

888 = 23 × 3 × 37;

888 is not a prime, is a composite number;

* Positive integers that are only dividing by themselves and 1 are called prime numbers. A prime number has only two factors: 1 and itself.

* A composite number is a positive integer that has at least one factor (divisor) other than 1 and itself.

Answer 2

Answer:

HCF By Prime Factorization Method

Follow the below-given steps to find the hcf of numbers using prime factorisation method.

Step 1: Write each number as a product of its prime factors. This method is called here prime factorization.

Step 2: Now list the common factors of both the numbers

Step 3: The product of all common prime factors is the HCF ( use the lower power of each common factor
