Question

Find LCM and HCF using prime factorization method
(I) 66 and 210
(II) 195 and 265

Answer 1

Hi friend !!

(1) 66 = 2×3×11

and 210= 2×5×3×7

L.C.M will be

2×3×11×5×7=2301

H.C.F will be 2×3 =6

(2)195= 5×3×13

265 =5×53

L.C.M =5×3×13×53

HCF =5

Thankyou..

Question -

Find LCM and HCF using prime factorization method

Find LCM and HCF using prime factorization method(I) 66 and 210

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 66 and 210 is 3×2 = 6

And

The LCM of 66 and 210 is 6×5×7×11 = 2310

(¡¡)

195 = 5×3×13

265 = 5×53

so,

HCF of 195 and 265 is 5

and

LCM of 195 and 265 is 5×53×3×13 = 10,335
