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.

@@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

Lcm means ( least common multiple ) ...... it means we have to take least number which is multiple for all so ....by your doubt we can also write 3× 27=>81 ......but it takes time to calculation... instead of having 27 as least common multiple we no need to take 81 ........ Whether if u take 81 also you will get same answer but it consumes more time. When you have big prime number then it is difficult to calculate so in that case we can go for prime number multiplication.

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.
