Solution: By prime factorisation, we can write the two numbers; 24 = 2 x 2 x 2 x 3 36 = 2 x 2 x 3 x 3 Hence, after factoring the numbers 24 and 36, we can see, the factors 2x2x3 are common. Therefore, the HCF (24, 36) = 2x2x3 = 12 ...
There are 3 methods to calculate the HCF of two numbers: HCF by the listing factors method HCF by prime factorization HCF by division method These methods are explained in detail with examples under the section How to find HCF? on this page. What are the Properties of HCF? The properties ...
HCF or Highest Common Factor can be found by using the Prime Factorisation method and Division Method. Learn to find HCF by shortcut method or formula with examples at BYJU'S.
So, we have, 56 = 2 × 2 × 2 × 7 and 84 = 2 × 2 × 3 × 7 . Now, HCF of 56 and 84 will the product of common prime factors with the lowest exponential power, that is, 7 and 2². So, HCF of 56 and 84 = 7 × 2 × 2 = 28. HCF of Two Numbers by Division ...
Method 2: Prime Factorization Using Factor Tree and Tabular Division From the word itself,Prime Factorizationis a method of getting the factors of a number that areprime numbers. Whether we are using Factor Tree or Tabular Division, our goal is to end up with prime factors, multiply them and...
3. Prime Factorization of 315: - Start with 315 and divide by 3: 315÷3=105 - Next, we factor 105, which we already did: 105=3×5×7 - Therefore, the prime factorization of 315 is: 315=3×5×7 Step 2: Identify the Common Factors - The prime factorizations are: - 70=2×5×...
