Question

the product of two co prime number is156 find the lcm

Answer 1

LCM will also be 156

Answer 2

We will use here a formula. That is of HCF × LCM = Product of the two numbers.


HCF of two co - prime numbers is always 1

So, HCF = 1

LCM of two co - prime numbers = ?


HCF × LCM = Product of two numbers

1 × LCM = 156

LCM = $\dfrac{156}{1}$

LCM = 156



∴ LCM = 156


Remember :- The product of two co - prime numbers is the LCM of that two co - prime numbers.
