Question

if two positive integers a and b can be expressed as a=43 and b=74 being prime numbers then find lcm and hcf

Answer 1

HCF of any two prime number is always 1
LCM of any two prime number is always equals to their product

Answer 2

Answer:

LCM is 3182 and HCF is 1

Step-by-step explanation:

Given two positive numbers which are prime we have to find the LCM and HCF.

Since prime numbers are only divisible by 1 and itself i.e having 1 and itself implies HCF of these are always 1 and LCM product of these two.

Given numbers a=43 and b=74 are coprime

43=1 x 43

74=1 x 2 x 37

implies no common factor except 1 gives HCF 1 and LCM the product of these two which is 3182.

LCM=1 and HCF=3182
