a. 12 and 48
​

Answer 1

12=2,2,3

48=2,2,2,2,3

LCM =48

HCF=2*2*3=12 answer

Answer 2

Answer:

Find the LCM of 48 and 12 by prime factorization method

Step-by-step explanation:

To find LCM of 48 and 12, write each number as a product of prime factors

20=2*2*5=2square*5

12=2*2*3=2square*3

Step 2: Multiply all the prime factors with the highest degree.

Here we have 2 with highest power 2 and other prime factors 3 and 5. Multiply all these to get LCM.

LCM of 20 and 12 =2*2*3*5=2square*3*5=60
