The lcm and hcf of 2 numbers equal
SpletClick here👆to get an answer to your question ️ Is the product of two numbers and the product of their HCF and LCM always equal? Consider any two prime numbers and check whether the product of their \\( \\mathrm { HCF } \\) and \\( \\mathrm { LCM } \\) is equal to the product of the numbers. SpletThe relation between HCF and LCM is, HCF of two numbers × LCM of two numbers = product of two numbers 6 × LCM of two numbers = 3276 Therefore, LCM of two numbers = 3276 ÷ 6 = 546 Example 3: Find the LCM of two numbers 20 …

Splet29. nov. 2024 · Time Complexity: O(n 2 * log(max(a, b))). Auxiliary Space: O(log(max(a, b))) Efficient Approach: If we observe carefully, it can be proved that the HCF and LCM of two numbers can be equal only when the numbers are also equal. Proof: . Let, HCF(a[i], a[j]) = LCM(a[i], a[j]) = K Since HCF(a[i], a[j]) = k, a[i] = k*n1, a[j] = k*n2, for some natural numbers … Splet07. apr. 2024 · Question Text. 2.

SpletLet us assume a and b are the two numbers, then the formula that expresses the relationship between their LCM and HCF is given as: LCM (a,b) × HCF (a,b) = a × b or, Product of the two numbers = LCM of the numbers × HCF of the numbers Difference Between LCM and HCF
SpletLet the numbers be a and b. We know that LCM × HCF = Product of the numbers. ∵ LCM = HCF. ⇒ LCM × LCM = a × b. ⇒ LCM 2 = a × b. It will be possible only when a = b. ∴ When …
