Question

find the highest common factor and lowest common multiple of 60 and 150 using prime factors

Answer 1

Here, we know, 60 = 2 × 30
& 150 = 5 × 30

So, Highest Common Factor (HCF) would be 30

Now, Lowest common point = 60 × 5 = 300 or 150 × 2 = 300

In short, LCM would  be 300

Hope this helps!
