Question

The LCM of two numbers is 210 and their HCF is 10 if one of the numbers is 30 what is the other number

Answer 1

Answer:

LCM X HCF = No1 X No2

210 X 35 = 105 X No2

210*35/105 = No2

2*35 = No2. (210/105 = 2)

No2 = 70

Answer 2

The LCM of two numbers is 210

and their HCF is 10

if one of the numbers is 30

then other number is y

lcm × hcf = x × y

210 × 10 = 30 × y

70 = y

the other number is 70
