Question

Find the LCM and HCF of 455 and 78 by using the prime factorization method. 455 = 5 × 13 × 7
78 = 2 × 3 × 13
HCF = 13
LCM = 2730

Answer 1

Answer:

HCF = 13

LCM = 2730

Step-by-step explanation:

Finding the prime factors of a given number, such as a composite number, is done through the process of prime factorization. The prime numbers are the only components in these factors. A number with just the number itself and factor 1 is said to be a prime number.

The least common multiple (LCM) is the smallest number which is a multiple of two numbers (LCM). The sum of prime numbers that equals a given number is known as its prime factorization.

455 = 5 × 13 × 7

and 78 = 2 × 3 × 13.

HCF = 13.

LCM = 2730
