Answer 2

Answer:

Two numbers can be (13,78) or (26,39).        

Product of two numbers = 1014

Step-by-step explanation:

Given : LCM of two numbers is 78 and HCF of two numbers is 13

To find : The product of two number and the numbers

Solution :

We, know that the product of two numbers = LCM × HCF

Using this property we can find the product of two numbers

LCM =  78

HCF = 13

Product of two numbers = LCM × HCF

Product of two numbers = 78 × 13

Product of two numbers = 1014

To find numbers we can do:

HCF = 13, means both the numbers have '13' in common.

LCM= $78=2\times3\times13$

So our numbers can be

$(13,2\times3\times13)$ or $(13\times2,3\times13)$

That is two numbers can be (13,78) or (26,39).
