Question

The ratio of two numbers 3;4 and their lcm is 60 find their hcf solution

Answer 1

let the nos. are 3x ; 4x
LCM = 3×4×X =12x
HCF = X
A.T.P; 12X = 60
X = 5
HCF = 5

Answer 2

Given : The ratio of two numbers 3:4 and their LCM = 60

To find :  HCF of given numbers

Step-by-step explanation:

Let say two numbers are

3x   & 4x

LCM would be

3 * 4 * x

= 12x

LCM is given = 60

Equating both

=> 12x  = 60

=> x = 5

HCF of 3x * 4x Would be

x

HCF = 5

Numbers would be 15 & 20

HCF = 5
