Question

1.Find HCF and LCM
of 72, 120
2.find HCF and LCM of 26, 91 and hence prove
НСfX LCM = Product of a nos.​

Answer 1

Step-by-step explanation:

Here

72 = 2 x 2x 2x 3x3

120 = 2 x2x2x3x5

CF = 2 x2x2x3

RF = 3 x 5

so,

HCF = CF = 24

LCM = CF x RF = 360

2)

26 = 2 x 13

91 = 7 x 13

CF =13

RF= 2 x 7

so,

HCF = 13

LCM = 13 x 2 x 7 = 182

Hence,

H.C.F x LCM = 26 x 91

13 x 182 = 26 x 91

2366 = 2366

Verified .
