  LCM of 12 and 18 To find out LCM (Least common multiple) of 12 and 18 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 12 and 18 first. *Multiples of 12 •12×1= 12 •12×2=24 •12×3= 36 •12×4= 48 ....................... *So the multiples of 12 are 12,24,36,48.....etc. *Multiples of 18 •18×1=18 •18×2= 36 •18×3=54 ..................... *So the multiples of 18 are 18,36, 54....etc Step-2:LCM (Least common multiple) of 12 and 18 means that the smallest multiple that both number (12 and 18) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *Multiples of 12 are 12,24, 36 ,48.....etc. *Multiples of 18 are 18, 36 , 54....etc Therefore,the smallest multiple that both number (12 and 18) share is 36. Answer:The LCM or least common multiple of 12 and 18 is 36.

  LCM of 9 and 12 To find out LCM (Least common multiple) of 9 and 12 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 9 and 12 first. *Multiples of 12 •12×1= 12 •12×2=24 •12×3= 36 •12×4= 48 ....................... *So the multiples of 12 are 12,24,36,48.....etc. *Multiples of 9 •9×1=9 •9×2=18 •9×3=27 •9×4=36 •9×5 =45 ..................... *So the multiples of 9 are 9,18,27,36, 45....etc Step-2:LCM (Least common multiple) of 9 and 12 means that the smallest multiple that both number (9 and 12) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *M ultiples of 12 are 12,24, 36 ,48.....etc. *M ultiples of 9 are 9, 18 ,27, 36 , 45....etc Therefore,the smallest multiple that both number (9 and 12) share is 36. Answer:The LCM or least common multiple of 9 and 12 is 36.

  LCM of 6 and 9 To find out LCM (Least common multiple) of 6 and 9 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 6 and 9 first. *Multiples of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 •6×7 =42 .................. *So the multiples of 6 are 6,12,18,24,30,36,42.....etc. *Multiples of 9 •9×1=9 •9×2=18 •9×3=27 •9×4=36 •9×5 =45 ..................... *So the multiples of 9 are 9,18,27,36, 45....etc Step-2:LCM (Least common multiple) of 6 and 9 means that the smallest multiple that both number (6 and 9) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *M ultiples of 6 are 6,12, 18 ,24,30 ,36, 42.....etc . *M ultiples of 9 are 9, 18 ,27, 36 , 45....etc Therefore,the smallest multiple that both number (6 and 9) share is 18. Answer:The LCM or least common multiple of 6 and 9 is 18.

  LCM of 4 and 6 To find out LCM (Least common multiple) of 4 and 6 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 4 and 6 first. *Multiple of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 .................. *So the multiples of 6 are 6,12,18,24,30,36.....etc. *Multiple of 4 •4×1=4 •4×2=8 •4×3=12 •4×4=16 ..................... *So the multiples of 4 are 4,8,12,16,....etc. Step-2:LCM (Least common multiple) of 4 and 6 means that the smallest multiple that both number (4 and 6) share. So in this step we will identify the smallest multiple that both number share or that is common in both number. *Multiples of 6 are 6, 12 ,18, 24 ,30,36.....etc . *Multiples of 4 are  4,8, 12 ,16,....etc Therefore,the smallest multiple that both number (4 and 6) share is 12. Answer:The LCM or least common multiple of 4 and 6 is 12. Next

LCM of 6 and 8 To find out LCM (Least common multiple) of 6 and 8 ,we will follow the following methods.         Method-01: Step-1:Find out the multiples of 6 and 8 first. *Multiple of 6 •6×1=6 •6×2=12 •6×3=18 •6×4=24 •6×5=30 •6×6=36 .................. *So the multiples of 6 are 6,12,18,24,30,36.....etc. *Multiple of 8 •8×1=8 •8×2=16 •8×3=24 •8×4=32 ..................... *So the multiples of 8 are 8,16,24,32,....etc Step-2:LCM (Least common multiple) of 6 and 8 means that the smallest multiple that both number (6 and 8) share.
