Assertion (A) : For any two natural numbers a and b, the HCF of a and b is a factor of the LCM of a and b. Reason (R) : HCF of any two natural numbers divides both the numbers.
Using prime factorisation, find the HCF of 180, 140 and 210.
The HCF of 95 and 152, is
The HCF of the smallest composite number and the smallest prime number is:
If two positive integers a and b are written as a = x³y² and b = xy³, where x, y are prime numbers, then HCF(a, b) is:
