WebMany students get confused and accidentally over-duplicate their factors, so let's spend a little extra time on this. Consider two smaller numbers, 4 and 8, and their LCM.The number 4 factors as 2 × 2; 8 factors as 2 × 2 × 2.The LCM needs only have three copies of 2, in order to be divisible by both 4 and 8.That is, the LCM is 8.You do not need to take the … WebSo the LCM is 2*2*2*2*3*3*5 = 720. By the way, there is a similar method of finding GCF (or HCF or GCD or HCD, where G means greatest, H means highest, F means factor, and D means divisor), but we use each prime factor the least number of times it appears in any prime factorization. In our example, the GCF would be 2*2*2 = 8.

WebThe product of given numbers is equal to the product of the HCF and LCM of natural numbers. I.e., LCM of given numbers × HCF of given numbers = Product of given numbers. To know more about the relation between HCF and LCM, click here. 9. Prove that LCM (12, 7) × HCF (12, 7) = Product (12, 7). WebStep 2: Mark the common multiples from the multiples of both numbers. Step 3: Select the smallest common multiple. That lowest common multiple is the LCM of the two numbers. Example: Find the least common multiple (LCM) of 4 and 5. Solution: The first few multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, ... WebThe HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.In simple words, the HCF (Highest Common Factor) of two natural numbers x and y is the largest possible number that divides both x and y. Let us understand this HCF definition using two numbers, 18 and 27. The … demineralizer for hair
