Question

The HCF of two number is 3 and their LCM is 120 if one of the number is 15.find the other number

Answer 1

hello users ...

solution:-
we know that:
for Any two numbers,their

LCM × HCF = Product of numbers

Here,
LCM = 120
HCF = 3 
And
first number = 15 
let second number = x 

According to Given:
120 × 3 = 15 × x

=> 15x = 360

=> x = 360/15 = 24 Answer 

# hope it helps :)

Answer 2

ab=hcf*lcm
$15a = 3 \times 120 \\ a = 3 \times 120 \div 15 \\ a = 120 \div 3 \\ a = 40$
