Answer 2

Question -

Find LCM and HCF using prime factorization method

(I) 66 and 210

(II) 195 and 265

Answer ==>

(¡)

66=2×3×11

210=3×2×5×7

so,

HCF of 66and 210is 3×2=6

And

The LCM of 66and 210is 6×5×7×11=2310

(¡¡)

195=5×3×13

265=5×53

so,

HCF of 195and 265 is 5

and

LCM of 195and 265is 5×53×3×13= 10,335

here is your answer.....
