Question

the lcm of two numbers 525 and 945 is 4725 . find their hcf

Answer 1

hcf×lcm=product of two numbers
hcf=(525×945)/4725
=105

Answer 2

Solution :-

We know that, 

Product of the two numbers = LCM × HCF

Two numbers = 525 and 945

LCM of two numbers = 4725

HCF of two numbers = ? 

⇒ 525 × 945 = 4725 × HCF

⇒ HCF = (525 × 945)/4725

⇒ HCF = 496125/4725

HCF = 105

So, HCF of 525 and 945 is 105
