Question

If HCF (4,b)=2 , LCM (4,b)=70 then the value of b is _____

Answer 1

Answer:

Value of b = 35 .

Step-by-step explanation:

We are given HCF (4,b)=2  and  LCM (4,b)=70

We know that;

     Product of two numbers = HCF of two numbers * LCM of two numbers

Here, two numbers are 4 and b .

        HCF of two numbers = 2  and  LCM of two numbers = 70

So,   4 * b = 2 * 70

         b = 140/4 = 35

Therefore, value of b = 35 .
