Q4 of 57 Page 31

The product of two numbers is 1080. Their HCF is 30. Then their LCM is:

We know the basic following relation:

HCF × LCM = 1^st Number × 2^nd Number

30 × LCM = 1080

LCM = 1080 / 30

LCM = 36

So correct answer is C.

If two numbers are written in the form of m = pq³ and n = p³q² then find the HCF of m, n when p, q are prime numbers:

The HCF (Highest Common Factor) of 95 and 152 is :

The decimal expansion of the number will be:

After how many decimal places with the rational number terminate?
