The HCF of a^6 - 1 and a^4+ 2a^3- 2a-1 is

LCM of two numbers is 12 times their HCF. The product of the numbers is 25920. What will be the maximum possible difference between the numbers?

The ratio of two number is 6 : 5 and their HCF is 15. So find and their LCM?

The greatest number, which when subtracted from 5260, gives a number exactly divisible by each of 12, 16, 20 and 25, is:

The LCM of two numbers is 216 and their HCF is 36. If one of the numbers is 72, the other number is:

The least number which when divided by 5, 10, 12 and 15 leave zero remainder in each case and when divided by 18 leaves a remainder of 6 is:

A number is three times another number and their HCF is 8. What is the sum of the squares of the numbers?

The smallest number which when divided by 28 and 32 leaves remainder 12 and 16 respectively is:

The LCM of two natural numbers is 8 times their HCF. If the product of given two numbers is 1152, then find the LCM of the numbers.
