because lcm.hcf is product all factors

Answer 2

Answer: 15

Step-by-step explanation:

As we know,

HCF × LCM = Product of two numbers

Given,

HCF = 5 & LCM = 30

One of the two number is 10

Let the second number be x.

Now, A/C above formula

10 × x = 5 × 30

=> x = (5×30)/10

=> x = 15.

Therefore, the second number will be 15.
