Find HCF of 96 and 404 by prime factorization method hence find their LCM with full procedure |
|
Answer» pls thank and 5 star Step-by-step EXPLANATION: Represent 96 and 404 as a product of its prime factors. Prime factorization of 96 is 2 × 2 × 2 × 2 × 2 × 3 Prime factorization of 404 is 2 × 2 × 101 HCF is the product of the factors that are common to each of the given numbers. Since, the common factors are 2 and 2, the HCF of 96 and 404 is 4 We will use the formula to calculate the LCM (a, b): LCM (a, b) = (a × b) / HCF (a, b) HCF (a, b) is the highest common factor of a and b. Using the formula, LCM (96, 404) = (96 × 404) / HCF (96, 404) By SUBSTITUTING the VALUES, = (96 × 404) / 4 = 96 × 101 = 9696 Therefore, the HCF of 96 and 404 is 4, and the LCM of 96 and 404 is 9696 |
