Question

Find the Lcm & HCF of 9, 12, 15​

Answer 1

Answer:

factors of 9 = 1 , 3, 9

factors of 12= 1, 2,3,6,12

factors of 15 = 1,3,5,15

LCM = 3

HCF = 1

Answer 2

Answer:

L.C.M

= 9 , 12, 15 = 2 × 2 × 3 × 3 × 5

= 180

H.C.F

= 9 = 3 × 3

12 = 2 × 2 × 3

15 = 3 × 5

common factor = 3

H.C.F = 3
