Answer:
HCF = 14
LCM = 1680
Step-by-step explanation:
Factorizing the given values
210 = 2 * 3 * 5 * 7
112 = 2 * 2 * 2 * 2 * 7
Since 2 * 7 is common to both factors
Hence the HCF = 2 * 7 = 14
For LCM, we we will multiply all the prime factors that are in both
LCM = 2* 2 * 2 * 2 * 3 * 5 * 7
LCM = 112 * 15
LCM = 1680
Hence the LCM is 1680
