why we find the HCF method by prime factors
Answers
The prime factor includes only Prime numbers.
In other words: any of the prime numbers that can be multiplied to give the original number.
Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).
"To find Highest Common Factor; Prime Factorization Method are Used".
STEPS to find highest common factor by using prime factorization method is discussed here.
Step I:
Find the prime factorization of each of the given numbers.
Step II:
The product of all common prime factors is the HCF of the given numbers.
Note:- These two steps are shown in figure.
