Question:
The [HCF × LCM] for the numbers 50 and 20 is
(a) 10
(b) 100
(c) 1000
(d) 50
Solution:
Here we have to find $H C F \times L C M$ of 50 and 20 .
We know the product of $H C F$ and $L C M$ of two numbers $a$ and $b$ is the product of $a$ and $b$. Therefore $H C F \times L C M$ of 50 and 20 is as follow
$H C F \times L C M=50 \times 20$
$=1000$
Hence the correct option is (c).
