Shortcut Explained: *Case 1* : no prime numbers present choose the largest number and check if it's divisible by all remaining numbers - if yes , then it's the LCM if no , then multiply it by 2 and check again if still not divisible , then multiply it by 3 and check again Repeat until it is divisible by all other numbers eg 12 6 24 8 *Case 2* : if prime present + other number are not divisible by it ( or in other words, other number is not a multiple of seven ) Example 1 : 4 6 7 7 is a prime and other numbers are not divisible by seven ( or they are not a multiple of seven ) - hence keep it (aside) Between 4 and 6 - 6 is greater which is not divisible by 4 6*2 = 12 is divisible by 4 So LCM = 12 * (7) = 84 Example 2 : 7 10 12 7 is a prime and other numbers are not divisible by seven ( or they are not a multiple of 7 ) - hence keep it (aside) Between 10 and 12 - 12 is greater but not divisible by 10 Then if we keep multiplying 12 by x1 x2 x3 x4 We will get 12x5=60 which is divisible by 10 So LCM = 60 * (7) = 420 *Case 3* : if prime present + other number are divisible by it ( or in other words, other number is a multiple of seven ) Then DO NOT keep it aside. Proceed normally like case 1 Example 1 : 7 8 14 7 is prime but 14 is divisible by seven ( or is a multiple of 7 ) Hence do not keep it aside.

sir in a short cut method you said take prime number separetly and multiple by the highest number but in eg. 3 and 4 there is also a prime number present there like 3 ...3 is also a prime number category ...in that case what should have we to do...please take it seriously and i hope yo will reply back and give appropraite answer which have we need

@@naazirayash9139 Bro ... in Eg 3 : 12, 3, 9 . Prime number is 3 but still 12 can be divided by 3(So dont consider 3 as prime number) So u can solve in the same manner u did for above 2 examples. in Eg 4: *3, 11, 12*. Prime No. are 3 & 11. But the remaining number (12) is divisible by 3 (so dont consider 3 as prime number here). But 12 is not divided by 11 (so consider 11 prime number & solve in the same manner like sir did)

Yeah .I also tried for finding the lvm by shortcut method .but it didn't work out. See 12,3,9 Pick 3 separately since it is prime 9,12 Highest no=12,(12/9=not divisible) 12×2=24,(24/9=not divisible) 12×3=36,(36/9=divisible) 36 is LCM for other 2 nos Check for 3×36 =108= LCM. But not correct . Rather find lcm for both 36(I.e LCM of other no's) and 3(prime no) LCM =36
