Question

Find the LCM and HCF of 75, 45, 105.​

Answer 1

Answer:

Step-by-step explanation:

LCM of the numbers = 315

We know,

HCF of 2 numbers  LCM of same 2 numbers = product of the two numbers.

Given that the 2 numbers are 45 and 105.

HCF of the 2 numbers = 15.

Hence, according to the formula  

HCF of 2 numbers  LCM of same 2 numbers = product of the two numbers.

15 x LCM of the numbers = 45 and 105

LCM of the numbers =  = 315  

Therefore, LCM of the numbers = 315
