A six digit number is formatted by repeating a three digit number: for example, 256, 256 or 678, 678 etc. Any number of this form is always exactly divisible by:

What is the highest common factor of 2x³ + x² -x -2 and 3x³- 2x² + x - 2 ? 

When a number is divided by 15, 20 or 35, each time the remainder is 8. Then the smallest number is 

The LCM of two numbers is 12 times their HCF. The sum of the HCF and the LCM is 403. If one of the number is 93, then the other number is. 

The greatest number, which when subtracted from 5834, gives a number exactly divisible by each of 20, 28, 32 and 35, is 

The H.C.F. of two numbers is 8. Which one of the following can never be their L.C.M? 

A, B and C start running around a circular field having circumference 144 metre at the same time from the same point. Speeds of A, B and C are 6 m/minute, 8 m/minute and 12 m/minute. Find after how much time, they will meet again at the same point for the first time.

The product of the LCM and HCF of two numbers is 24. The difference of the two numbers is 2. Find the numbers?
