​

Answer 1

hope this helps u

given

hcf = 18

lcm= 1782

one number = 162

another number be x

we know that  hcf* lcm= product of two numbers

18*1782=162*x

x=18*1782/162

x= 32,076/162

x=  198

another number is 198

verification

hcf * lcm = product on two number

18*1782= 162*198

32076=32076

Answer 2

Given : The HCF and LCM of two numbers is 18 and 1782 respectively. one number is 162,

To find  :  the other number​

Solution:

HCF ( a, b) * LCM ( a , b)  = a * b

HCF ( a, b)  = 18

LCM ( a , b) = 1782

a = 162

=> 18 * 1782  = 162  *  b

=> b = 198

Hence other number is 198
