1. Find the greatest common divisor of the term 144x3y2and 81xy4

Step-by-step explanation:

Given the terms:

and

To find:

Greatest Common Divisor of the two terms or Least Common Multiple (LCM) of two numbers = ?

Solution:

First of all, let us find the HCF (Highest Common Factor) for both the terms.

i.e. the terms which are common to both.

Let us factorize them.

Common terms are underlined.

So, HCF of the terms =

Now, we know the property that product of two numbers is equal to the product of the numbers themselves.

HCF LCM =

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
