Question

12 , 15 , 18 ka H.C.F or L.C.M find please gives answer​

Answer 1

Step-by-step explanation:

HCF => Highest common Factor

12 = 1 , 2 , 3 , 4 , 6 , 12

15 = 1 , 3 , 5 , 15

18 = 1 , 2 , 3 , 6 , 9 , 18

Common Factor => 1 , 3

Highest in common factors => 3

therefore HCF is 3

LCM => Least common Multiple

12 = 12 , 24 , 36 , 48 , 60 ................ , 120.....

15 = 15 , 30 , 45 , 60 , 75 ........... , 120

18 = 18 , 36 , 54 , 72 , 90 ,.......... , 120

Least in common multiples will be 120

therefore the LCM is 120

{ here , 120 is the least number which is a multiple of 12 , 15 and 18 }
