Question

7) The product of two numbers is 180. If their HCF is 3, What is their LCM?
place answer the question step by step ​

Answer 1

ANSWER

For two numbers a and b, we know that

( a × b ) = {HCF of ( a, b )} × {LCM of ( a, b)}

Here a × b = 180, HCF = 3, So we have

to find b.

➡️ 180 = 3 × L ( L means LCM )

➡️ 3L = 180

➡️ L = 180

3

➡️ L = 60

Hence, LCM is 60

Answer 2

$\huge \mathfrak \red{Ãñßwèr}$

$\huge \bf \pink{given}$

$= \red{xy = 180}$

$= \red{HCF = 3}$

= HCF×LCM=product of two numbers

= 3×LCM=180

$= LCM = \frac{180}{3} = 60$

= LCM=60
