Heya!

Here is yr answer.....


Given,

HCF of 28,35 and 343 = 7


LCM = ??


Now,

According to prime factorization.....

28 = 2² × 7

35 = 5 × 7

343 = 7³


LCM = 7³ × 2² × 5 = 343×4×5 = 6860


Therefore, LCM of 28 , 35 and 343 = 6860


Hope it hlpz...

VijayaLaxmiMehra1: But this process is not right by prime factorization

We know that,

HCF× LCM=Product of given numbers

7×LCM=28×35×343

7×LCM= 336,140

LCM= 336,140/7

LCM= 48,020

Hence, LCM (28,35,343) is 48,020...

HOPE it helps!!!!✌️
