In this article, we will find HCF of two numbers using factorisation and division method, with the help of solved examples. Also, find the HCF of three numbers, here at BYJU’S.
Let us see with the same example, which we used to find the LCM using prime factorization. Solve LCM of (60,45) by division method. Therefore, LCM of 60 and 45 = 2 × 2 x 3 × 3 × 5 = 180 At BYJU’S you can also learn,Prime Factorization Of Hcf And Lcm. ...
LCM by Prime factorization To find the LCM using prime factorization method we need to follow the below-mentioned steps: Find the prime factors of numbers individually. From all the factors, identify the maximum number of times each prime factor appears. ...
Express each of them as a product of prime factors using prime factorization. For example, if we take the number 18 , it can be broken as 2 × 3². Similarly, factorise each of the numbers. Now, the product of all these highest powers of prime factors will be equal to the LCM. ...
