Question

few own numbers for LCM & HCF by prime factorization method

Answer 1

Step-by-step explanation:

Start by writing 24 and 180 as the product of their prime factors. To find the HCF, find any prime factors that are in common between the products. Each product contains two 2s and one 3, so use these for the HCF. To find the LCM, multiply the HCF by all the numbers in the products that have not yet been used

Answer 2

Answer:

Prime factorization of 6 and 20 is (2 × 3) = 21 × 31 and (2 × 2 × 5) = 22 × 51 respectively. LCM of 6 and 20 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 22 × 31 × 51 = 60. Hence, the LCM of 6 and 20 by prime factorization is 60.
