(b) 130, 195 and 390
(c) 252 and 576​

Answer 1

Answer:

(b) 130,195 and 390......

Answer 2

$\underline{\pink{ Finding \: HCF \:Division \:Method : }}$

$1. Given \: 120, 128 \: and \: 496$

120 | 128 | 1

****** 120

____________

*********8|120|15

***********120

____________

*********(0)

HCF (120, 128 ) = 8

Now, we have to find HCF of 8 and 496.

8 | 496 |62

****496

________

*****(0)

HCF ( 8,496 ) = 8

Therefore.,

$\red{ HCF (120,128\: and \: 496)} \green { = 8 }$

$2. Given\: 139, 195 \:and \: 390$

130|195| 1

**** 130

___________

******65| 130|2

********** 130

___________

**********(0)

HCF (130,195) = 65

Now, we have to find HCF of 65 and 390.

65| 390|6

**** 390

_________

******(0)

HCF (65,390) = 65

Therefore ,

$\red{ HCF (130,195,390) } \green { = 65}$
